TANK GIRL!
Riki-Oh: Story of Ricky: exploding styrofoam heads and hands. Mints stored in a glass eye. Severed tendons tied together. And the warden! Hoo boy, the warden.
Evil Dead Trap: I did a full review of this in the Pit some time back. It was just tremendous.
Bad Taste: Peter Jackson’s debut film. You owe yourself the viewing of it.
Cthulhu Mansion: Tormented magician with huge eyebrows lives in a mansion with “Cthulhu” written over the gate. A small gang of hoodlums invades. Hilarity results. Also starring a character with a very long build-up, and very rapid demise.
Deathstalker II: Watching this is sort of a tradition with a friend of mine. He just got it on DVD. His wife was…less than thrilled.
I actually will admit to liking Mannequin 2.
“Spacehunter : Adventures in the Forbidden Zone” - anyone remember that?
Molly Ringwald + evil Michael Ironside + that guy from Kane & Abel + lots of bimbos skipping about = one guilty pleasure.
Spacehunter: Adventures in the Forbidden Zone - yeah, I remember that. Yes, it’s bad. Yes, I like it. I remember seeing it at the theaters where IIRC, it was shown in 3D.
Labrynth - this is a bad movie? I love Labrynth! David Bowie is too cool as the Goblin King and ya gotta love his song numbers with evil looking muppets. 
Evil Dead Trilogy - all three of them. Wish they made more. This stuff is high quality crap.
The Rocky Horror Picture Show - I know it has its followers, and I’m one of them, but without yelling at the screen and throwing rice and toast, it’s crap.
Track of the Moonbeast - I had seen this and made fun of it with my cousin before I knew MST3K had gotten hold of it. And on the subject, many many thanks to Tars Tarkas for giving me a copy of the MSTied version at the last St. Louis DopeFest.
Cal- OH SNAP, you are quite right, I’m thinking of Sinbad of the seven seas. Dang, don’t you worry though, I have properly flogged myself for this grevious error.
You are right about The Seventh Voyage of Sinbad-it’s a good movie as well.
Widdershins- That would be the movie! Lou being dubbed and climbing very obvious rubber snakes…What could be better! Killer Clowns kicks ass!
Red_dragon- I totally agree, Tank Girl was good. I found Lori Petti strangely erotic in that flick.
For the record I do not find any of the evil dead trilogy to be associated with “bad” movies. They are B movies for sure, but I prefer to think of them as “Life changing experience” movies.
Earth Girls Are Easy with a cast (Geena Davis, Jeff Goldblum, Michael McKean and a young Jim Carrey) who should have known better.
Rocky Horror Picture Show, I agree with Crunchy. As much as I love Tim Curry…
If it’s been on MST3K…especially Manos-the Hands of Fate and Alien From LA.
Elvira, Mistress of the Dark, cool car, flat jokes
King Solomon’s Mines, the Golan-Globus one, so many inconsistencies that it’s funny.
I can’t believe I’m the first one to mention this, but since nobody else mentioned it : Attack of the Killer Tomatoes !
And two local ones :
La petite Aurore, l’enfant martyre, this melodrama is so over the top that you can’t help yourself laughing in spite of the gravity of the subject .
And
IXE-13, based on a local pulp that ran in the 40s and the 50s about a French-Canadian secret agent. Extremely campy.
Oh, hardygrrl ? You know that there is a sequel to Alien from L.A. ? It’s called Journey ti the Center of the Earth (another Golan-Globus production).
Holy monkey crap! I’m not the only one who’s seen Richard Elfman’s movies! To BurnMeUp’s two, I’d like to add Modern Vampires starring (and I use the term loosely) Casper Van Dien.
I’m also a big fan of:
The Evil Dead trilogy
TftC presents: Demon Knight
From Dusk 'Til Dawn
and doubtlessly more, but I have to get back to work. 
Ah Zacherley! I also have his record. It’s buried in one of these piles somewhere. Zacherle has a brief appearance “Thunderstorms tonight! Great wheather for all you mad scientists out there!” in-
Frankenhooker-Man’s wife killed in horrible remote-controlled lawnmower accident. Using his skills as an electrician, and her preserved head, he endeavors to ressurect her.
Blood Harvest-The American Dream is over for these people. Farm after farm is foreclosed. The despair puts one person over the edge. A serial killer is on the loose in the heartlands. Stars Tiny Tim (Yes, tiptoe-through-the-tulips Tiny Tim)
Dr Caligari-Not Cabinet Of Caligari or Cabinet Of Dr Caligari. The first 30 minutes or so feature no dialogue. The rest is dystopian, expressionist ride through the depths of insanity. Everyone I’ve shown it too declares it genius or calls it nausea inducing pseudopornography.
Howard The Duck-Sure, it doesn’t measure up to ET. But, viewed on its merits, it’s an enjoyable film. Unlikely hero saves the world through self-sacrifice and winds up with the girl. Jeffrey Jones (Mom And Dad Save The World, Ed Wood, Stay Tuned, Ferris Bueller’s Day Off) plays a brilliant scientist possessed by a Dark Overlord Of The Universe.
Battle Beyond The Stars-Stars that guy who played John Boy Walton. Boy from hick planet sets out on junker star ship to save his colony from the forces of the evil Zadar. Loosely based on Kirosawa’s The Seven Samurai.
Trancers, PuppetMaster, Etc- These movies were made independently then bought by Full Moon. Full Moon distributes them and makes a bunch of awful sequels. The originals are often genuinely good films.
Trancers-Jack Deth travels back in time to stop the evil Whistler from killing his enemies ancestors with his zombie armie.
PuppetMaster-Andre Tulon discovered a way to bring his puppets to life. Forty years later his secrets, and his puppets, are unearthed. A group of psychics in an abandoned hotel try to figure out what the hell’s going on and what to do about it before it’s too late.
David Cronenberg’s The Fly-Once you get past all the gore and oozing fluids, the film has a lot to say. Brundle (Jeff Goldbloom) goes from viewing his transformation with fear and disgust, to being outright gleeful about the deformation and loss of body parts. Minor Spoiler-Watch carefully as he puts his teeth in the medicine cabinet and gives the ‘Relics’ speech. Beside his ears and other parts, Brundle has placed his penis in the “Brundle Museum Of Natural History”.
children at play i can’t describe it. you just have to see it to beleave it. great ending!
I like a bad movie. If you’re really into this sort of thing, you may wish to read the amusing books by L.A. Morse “Video Trash and Treasures”. Never understood what folks saw in Joe Bob Briggs.
Favourites of mine include:
Sssssssss - attack of the intelligent toxic gas
Zebra in the Kitchen - pretty much describes it
Santa Claus Conquers the Martians - Go Pia!
High School Caesar (and other Teenage Theatre)
Faster Pussycat, Kill! Kill!
Attack of the Killer Tomatoes
Metalstorm: The Destruction of Jared-Syn
Don’t much like some of the intentionally bad movies, e.g. the Troma Team stuff
The review of Boxing Helena is of particular beauty. Don’t say I never gave you nothin’.
No problem. Just keep singing “California Lady…”
The Toxic Avenger
Attack of the Killer Tomatoes (“You should see what she can do with milk bottles and a tuning fork!”)
and the Japanese film Versus
Track of the Moon Beast is pretty bad, but how about Hobgoblins? That was just people being attacked by plush toys!
Actually, pretty much any of the MST3K movies will qualify; I have about 100 on cd, and am still getting more!
When I was in college I was part of a test audience for this movie - sat through the whole thing and then filed out a “what did you think of it?” questionaire.
It was released anyway.
Mercifully the years had blotted out most of my memories of that initial viewing, until I saw a listing for it on one of the cable channels and out of morbid curiousity watched it to see how they had managed to salvage the disaster I had seen into a watchable movie.
They hadn’t.
A few favorites from my high school days in the 80s:
Cannibals in the Streets
Terror Train This one had David Copperfield!
Good stuff. 
Sheri
Plan 9 From Outer Space, Glen or Glenda, Bride of the Monster, or just about anything else by Ed Wood. If you’re into Ed Wood, check out the biographical move Ed Wood by Touchstone Pictures. This is actually a GOOD movie but it kind of fits in this category because it’s about someone who made horrible movies. Bravo has been showing it recently.
Some others:
Killer Klowns From Outer Space
The Attack of the Killer Tomatoes
The Incredibly Strange Creatures Who Stopped Living and Became Mixed-up Zombies. IIRC this was billed as “the first monster musical”. It’s practially unwatchable but I love the name.
