That’s the one I was going to mention. Here’s the YouTube link [NSFW: language]:
The computer I’m on right now doesn’t have sound. What’s the line?
Pretty please?
Guy says “…I’m really wired, how about I take you home and eat your pussy?”
And it works 
It’s pretty obscure and archaic but there is an explanation. When oxen were used as draft animals they were yoked side by side. Because the driver walked on the left side of the team, so as to wield the goad with his right hand, the left hand ox was the “near ox” and the right hand ox was the “off ox.” Thus “Adam’s off ox” is someone remote from you in time and distance, that is, someone you don’t know and would have no reason to know. My father, who specialized in obscure and archaic language used it often.
Now try to figure out “he stacked arms at Appomattox.”
Do you want me to order a pizza? I already ordered a pizza…
What…that line doesn’t usually work for you?
“Pierogies! Cheese and Potato!” - Holloway from Cube.
Which, I always took as a WTF line offered as an answer to the question “How did we get here*”.
*Here being inside the Cube structure itself.
But, I guess it also works that she was trying to remember her last moment before being put into the cube.
Then again, given the time, I could come up with a few also ran WTF lines from Cube. And a few Knock it out of the park, put that in your pipe and smoke it lines.
Weird Canadians. I love Cube and from an allegorical and minimalist standpoint, given it’s budget, I think it is a superb film. YMMV.
I just thought of another one, from Cabin Fever:
“Pancakes…PANCAKES!!!”
(kid does a spinning jump kick then bites a dude’s hand.)
Seriously, WTF?
Holy crap. I love how the octopus’ tentacles are supposed to be grabbing them, but the goonies are just kinda leaning on them, the way you’d lean on the edge of a swimming pool.
This isn’t a big WTF that ruins the movie or anything, but talking about deleted scenes and such reminded me of the Princess Bride, after the Prince put Westley though the machine on its highest setting. Inigo hears the sound, and figures out that it has to be the Man in Black, going through ultimate suffering. When Fezzik asks why:
“His true love is marrying another tonight, so who else has cause for Ultimate Suffering?”
Which is all very nice, except - how do either of them know that Westley and Buttercup are true loves? Neither of them saw anything while interacting with the Man in Black to give them an idea of his motives for chasing the princess, and nothing was explained about how they’d have learned it afterward. Inigo just needs to know this for the plot to continue on, so he says the line.
I think that the book mentions something about this, but I don’t even remember how good of an explanation it was.
Please tell me that somewhere on the internet is a clip of that line, then a cut to a guy sitting at the dining room table, eating what is obviously a roasted cat. 
As for the line itself, it truly is a WTF? moment. I can only imagine how that went with the actors, director, and writers - “Are you friggin’ kidding me? Who says that?”
I’m going to, at my very next opportunity. I’m sure it will go swimmingly.
Would you mind filming it and posting it for us to see? That would be AWESOME!
I understand that the bite was scripted, but the line was an ad lib on the part of the kid. It was so weird they decided to leave it in.
The line was ad libbed by John Barrowman. I’ve heard that he said it as a joke just to see how his costar would react. He did not expect it to be left in the film.
So what I’m getting is that I’m like, the only guy ever who actually liked that line, including, from what I’ve read, the guy who wrote it. I figured it was just Storm telling off Toad, like he’s nothing special (which, for a mutant in Magneto’s gang, has gotta be one hell of a diss)
At least, that’s how I interpreted it.
Good one. That movie also had the old hillbilly dude in the store telling them that the reason he has a big gun is “for the niggers”, which even the characters in the movie WTF at.
turns out he’s just a cool (:rolleyes:), hip hop old hillbilly dude, and “his niggaz” are coming to get the gun from him
Lethal Weapon 3 has the line "Close is a lingerie shop without a front window. " It is never explained.
And another, from 8MM
“Did you watch it with him? The snuff film…did you watch it with him? Did it get him off? Watching them cut her up? Did he jerk off to it? DID YOU HOLD HIS COCK AND GIVE HIM THE HANDJOB WHILE MARY-ANNE WAS DYING?!”
Now, this makes perfect sense as part of the plot, but it’s a “WTF line” of a “WTF-were-they-thinking-when-they-let-that-piece-of-shit-take-get-into-the-final-film” kind. Seriously, Nic Cage delivered one of his worst performances with that one short sequence.
Don’t even get me started on The Wicker Man
Pull the string! PULL THE STRING!!!
