Probably Stinky Pete’s blooper in TF2
Never was a fan of fart jokes.
[spoil]BUT REMEMBER, ALL THAT SNOW AND GRIME CAN RUST YOUR BOLTS AND FREEZE YOUR…[/spoil]
Yeeeeah, forced joke to cater to older fans = no thx.
I don’t think it’s the worst…
The worst would probably be “Let’s see how much we’ll go for on ebay”, said by Hamm in the Toy Story 3 trailer. 
In the case of that line the joke would actually be Mike mocking what Randall just said and saying to Sulley “One of these days I… am gonna let you teach that guy a lesson!”, and that WAS funny.
I can’t really think of a worse joke at the moment, but I’m sure there’s one somewhere in Cars.
EDIT: I just thought of one. It’s right before Guido changes Lightning’s tires in the final race and Chick Hicks’ pit crew tells him “Those round things are called TIRES, and they’re supposed to go UNDER the car!”. What does that even mean?
Haha, I quite liked that joke, TAMATER.
I think the emphasis of that joke, Flik-E, is the sarcasm, as Chick Hick’s pit crew is trying to make it sound as though Guido knows absolutely nothing about changing tires, not even where they go or anything like that, though I agree that it’s not particularly funny.
When marlen says “So just then,the sea cucumber looks over to the molluk and says-with fronds like these, who needs anemones.”
If that is then I guess the irony would be that it’s the point in the film where Marlin finally knew how to tell a good joke.
Really? I found that line pretty sad.
Worst joke? I don’t know. Cars has the most I know that for a fact…
I really think this line just represents Muntz’s character and his own personal sense of humor. I don’t think it was intended to be a joke for the audience. I don’t know though really…
Oh I agree with the whole fart jokes thing; not a fan.
Since that joke was only for fun at the end of the film though and not really a part of the story, I’ll give it to them.
Edited. I combined both of your posts. – Mitch
I have to second (third?) that motion about the fart jokes.
I do really hate toilet humor, scatalogical, flatulence, and whatever the heck kind of humor that involves farting, poop, or burping. Whenever one of these manages to creep in a film, I lose respect for said film immediately. Though considering those in TS2 were in the credits bloopers I forgive them.
(then could somebody explain why I was lol’ing the whole time during the fight with the Great Mighty Poo in the game Conker’s Bad Fur Day??!)
Yup, yup.
On RARE occasions it can be funny, as long as it isn’t all ‘in your face’ like. Ya know? Ah, I’m rambling once more…
Probably, in A Bug’s Life, when Hemlich is "lifting off" for the first time, he yells "You all look like little ants." Seriously, Pixar. That’s uber-cliche.
Worst joke?
Definately, “I’d give my left two lug nuts to work with her”. 
That joke is VERY naughty, if you know what it means. And to think, it was in a Pixar film!
Was that an intentional pun?
Why don’t you guys like, “Get off of his roof”? The worst joke is in Toy Story 3 when Hamm says, “I don’t think those were linkin’ logs.” >_>
In Toy Story when Andy’s first present is a lunchbox and Mr Potato Head says “A lunchbox?” And Slinky replies,
“For lunch!” and starts laughing.
Yeah, I wasn’t a fan either.
The fart jokes by Prospector during the credits of Toy Story 2. Fart Jokes are not funny, even if by Pixar. At least it was only during the credits.
The part in Toy Story 3, where Lotso says “FAO my Shorts” or something? I don’t get it?
It’s a reference to the toy company FAO Schwarz.

Agreed. I’m surprised at the amount of adults that laughed at that… maybe cuz the little ones didn’t quite get it.

Ehh I don’t like that one much, either. The "He did [i:icxu5c2f]what[/i:icxu5c2f] in his cup?!" was more tolerable and at least laughable. Of course, half the jokes in [i:icxu5c2f]Cars[/i:icxu5c2f] make me cringe anyway… so maybe that’s sort of why I’m not such a big fan anymore. A lot of it just seems too forced.
