This old silly joke about pizza I once heard.
This guy is starving, so he tells his co-workers, “I’m going to go get a large pizza, I’m so hungry”!!
So he goes to the pizza store, and tells the guy behind the counter, “I’m starving, give me a large pizza”!!
The pizza guy says “okay, you want that cut into 8 or 12 slices”??
The man says “Oh heavens, EIGHT!!! I could never eat 12 pieces of pizza”!!!
Laurel and Hardy. Not all of their stuff, but several classics.
While I have yet to read ‘A Walk in the Woods’ by Bill Bryson, if it is anything like his other stories, it is sure to be a whole hoot of funny stuff.
But YMMV of course.
And I’m with Superstar with her accolades about Ab Fab…no matter how many times I see the series, it never ceases to make me guffaw and snort into my Vodka.
That guy in the Weird Al movie, UHF, who kept screaming, “STOOOOPIDDDD!!! You’re so STOOOOOOPIIIIDDD!!!”
Steve Martin’s performance of “King Tut” on Saturday Night Live.
Leslie Nielsen as Frank Drebin pretending to be opera singer Enricho Palotzo and the home plate umpire in “Police Squad: The Naked Gun.”
The Latin grammar lesson scene from “Monty Python’s The Life of Brian.”
Jim Ignatowski’s drivers license test on “Taxi”:
“What does the yellow light mean?”
“Slow down.”
“Whaaaat does thaaaaa yelllllllllloooooo light mean?”
“Slow down”
“Whaaaaaaat does thaaaaaaa yellllllllllllloooooooo light mean?”
“Hi. I’m Larry. This is my brother Darryl, and my other brother Darryl.”
Steve Martin in The Jerk when he is leaving his mansion … all I need is … then he gets to his dog and the dog growls at him. 
Or when he tells his girl he’s going to buy her a diamond so big it will make her puke, and she replies, “But I don’t want to puke”.
Just way too many gags in that movie to list them all …
The Big Lebowski. I used to have it in my VCR at all times, just start it up where it left off, rewind at the end.
I knew a group of guys that used to get together once a month for Lebowski night. Every time The Dude lit one up, so did they, every time he made a Caucasian, so did they. Crazy bastards
Chris Farley, RIP.
Also, MAD comics. Don Martin, etc.
Yet another vote for Mr. Bean. He made my son laugh so hard he peed all over himself and then he didn’t want to leave the room because the show was still on. I think I’ll buy the DVD set for Christmas.
Potty humour. Oh my. Someone overflowed the bathroom at work and they sent in a shopping cart guy to clean it up. You could hear him yelling in there about FECES all over the PLACE. He then asked for a dustpan from the deli to SWEEP up the FECES. After that he went back to bagging groceries and still was talking about having to clean up FECES. It was the funniest thing and we were hanging all over each other laughing. Poor guy.
My son jumping on me, saying “I love you!”, and farting.
Monty Python, Blackadder, and Keeping Up Appearances.
Threads where lieu posts (yay potty humour!)
With me, it’s Stuart. “JUMPING JESUS ON A POGO STICK! Don’t you know that burrow owls live. In a hole. In the ground?! Why the hell do you think they call 'em burrow owls, anyway?!”
Billy Connolly describing swimming in the North Sea. That routine should come with a health warning.
Oh, and people walking into lamposts or falling down holes.
And farts, obviously.
Carol Burnett and the rest of the cast in “Went With the Wind.” Just thinking about her in the dress made from the drapes (with the curtain rod across her shoulders) cracks me up every time.
Amos and Andy radio and (the sadly aborted) TV series.
For crying out loud, isn’t somebody going to pull my finger?
Uhhh… is that you Grandmom?
Red Dwarf (every episode except for Camille)
George Carlin
Mel Brooks movies
Recess, the cartoon. Don’t ask. Gotta love that show.
I Love Lucy.
My kid brother.
Lucille Ball auditioning for the Vitameatavegamin pitchgirl.
Kids in the Hall “I’m crushing your head” bits
Pulling Cervaise’s finger

Heh heh heh.
Mmmmmmm… It’s so tasty, too!

I am not that old, I saw the episode on Nick at Nite in the 90’s, while other Lucy sketches look dated, this one remains fresh.
