Most Pixar films that don’t have bloopers after the credits have a topic somewhere on the forums where people can make their own - I though it would be fun to start one here.
Post away!
i would laugh if they made another bugs life 2 blooper 
How about trying to get Buzz’s Spanish Mode on but it keeps coming out in the wrong languages instead, like Japanese? Probably would get confusing.
I would maybe do a blooper where a kid eats Mr or Miss Potatoe Head mouth, and where everyone panics to find it and everything like that.
- Mr. Pricklepants steps out of character after a cut
- Ken trips while trying on outfits
- Bookworm keeps hitting someone with the Buzz Lightyear manual
- The dump truck can’t stop when it arrives
- Someone else slips on the puddle in the bathroom
Lotso: “You know Ken, I’m sure I can get you a part in Toy Story 4…”
- Woody’s pull string snapping as he falls from the tree.
2)Andy falling off his chair when he looks in the toy box.
3)the tortilla holding up Mr. Potato Head rips. - Instead of it being Barbie wearing the heels in Ken’s astronaut suit, it’s actually Ken.
- Ken can’t get the Dream House elevator to work.
Molly/Andy out take-
“Can I have you stereo?”
“Sure - wait no, rats!”
Rex- “And Bo Peep”
Woody- “Yeah, … and Bo”
Director- “Cut and print!”
Bo comes onto the set
-Omar
Show them filming the Daycare torture and then ‘cut’ and they’re all thrown on the floor, then you see the real toys off-set and Buzz says “Thank goodness for stunt doubles”
[spoil]Barbie twists Ken’s head around to get him to tell her what Lotso did to Buzz, and Ken burst out laughing.
In the credits, Woody doesn’t throw the rose to Jessie, but puts it in his own mouth and mocks Buzz’s dancing.
The crow doesn’t peck at Potato Head’s tortilla, leaving Potato Head standing there on the sill.
After the cameras stop on the Potato Head in a cucumber scene, he says he actually liked the fresh feeling
After the last scene, Andy drives back down the street to Bonnie’s house and they all drink sodas to celebrate the end of filming. [/spoil]
Trixie and Rex go off set together after filming the keyboard scene for the credits. Ahem ahem. -Omar
EDIT- I’ve added spoiler tags to potential spoilers.

[spoil]- In the climax, Lotso throws Ken to the other side of the dumpster, but Barbie doesn’t realize they were filming and so she doesn’t grab onto his arm to help him up.[/spoil]
EDIT- I’ve added spoiler tags to potential spoilers.

Woody and Potato Head are filming the opening sequence.
Woody: You’ve got a date with justice…
Potato Head lets out a nasty fart, like Stinky Pete
Woody: Pee-yeew!!! I think I should call you “One Eyed Fart!”
If there could be one fart joke in Toy Story 3, that would be it.
When Buzz climbs up inside the vending machine, he sees a pack of Twinkies.
“This daycare ought to be reported for stocking expired food substitutes!”
[spoil]Instead of Andy’s phone number on Buzz’s wrist communicator, its a 1 900 number.
Bonnie pushes Buzz’s chest button and he farts
The peas in a pod want to get adopted by the Potato Heads too
Woody wants to stop Sid from taking the trash, so he redoes his voicebox scare tactic on Sid, “Remember me? Sid Phillips?”
Bonnie says There’s a snake in my boot, but when Andy pulls Woody’s string, it says something else. Or he farts[/spoil]. 
-Omar
-During Buzz and Jessie’s dance, one of them forgets the next part of the dance and they both fall to the floor.
-When Spanish Buzz dances around Jessie, instead of standing there with a confused look on her face, Jessie starts to laugh.
[spoil]-Andy’s mom gets in her van to drive the toys to Sunnyside, but the car doesn’t start.
-During the Fashion Show scene, Ken accidentally dresses up in one of Barbie’s dresses.
-There is a delayed explosion for the dynamite that is on the train tracks in the opening sequence. When it finally explodes, it doesn’t do anything. It’s as if a firecracker like explosion went off and nothing more happens.
-When the toys go down the garbage chute, they all slide into the dumpster.[/spoil]
EDIT- I’ve added spoiler tags to potential spoilers.

Guys, even though we’re obviously talking about bloopers here, some of you are revealing quite a few details that I and other people may not want to know about before seeing the film. I’ve edited a fair few posts but it’s difficult to draw the line, so a good rule of thumb is if you didn’t know about it before seeing the film, add spoiler tags!
My sincere apologies. 
[spoil]When the toys bring the gym sock into the toychest, it stinks and they all open the box to get air.
In the credits, along with Zurg and other toys, Stinky Pete comes out of the cardboard box, and he’s covered with crayon scrawls by Amy
After the Lotso flashback scene is filmed, Daisy drops the new Lotso and hugs the original one.
After filming is over, Ken hands Big Baby the real toy pendant and shows that the one that Lotso broke was a duplicate
In the credits, Ken drinks Big Baby’s bottle instead of letting Barbie give it to Big Baby[/spoil] -Omar
Whoops, sorry about the spoilers. It’s easy to forget that some people haven’t seen it already. 
Sorry for posting again, but now that I’ve actually, you know, seen the movie, I have some more bloopers.
[spoil]- Lotso: But just you wait. You’ll find being donated was the best thing that ever happened to 'ya! (accidently hits kitten toy with cane)
Kitten toy: OW! Seriously, this is the forth time you’ve done that!
-
(Woody and the Monkey sit up and look at each other after Woody fails at putting the bag over his head)
Monkey: … What’s my line? -
Barbie: Oh, a Nehru jacket!
Ken: Barbie, not the Nehru!
Barbie: This is from what, 1967?
Ken: The groovey formal collection, yes!
Barbie: What a shame. (Rips jacket in half)
… Wait, I wasn’t supposed to do that, was I?
Ken: Noooooooooooo! -
{In the credits} (Ken tears off his jacket and instead of revealing his gold suit, he’s in his underwear)
Ken: (To ‘camera man’) Hey, wait! Are you still filming? NOT COOL! (Storms off)[/spoil]
That would be so funny to see!
