How about this blooper?
"Land of the Flea"--Eduardo...hairless, take one

(The blooper begins with Eduardo shouting...)
Eduardo: NOOOOOOOOOOOOO! (He is mostly hairless, leaving his arms in fur.) What did you do? What did you do?!
Craig: (off camera) Cut!
Eduardo: What?
Craig: (off camera) You still have fur on your arms.
Lauren: (coming in) Why is it that you're mostly furless?
Eduardo: I dunno. I just wanted to see if it was funny.
Craig: (coming in, rubbing Eduardo's shoulder) Can we take two?
(The blooper ends.)

From Good Wilt Hunting
Scene: Wilt looks lonely

Craig: CUT!
Wilt: What?
Craig: You're supposed to look pitiful and lonely and sad. Not joyious and happy right now!
Wilt: ...I'm sorry but why?
Craig: It's what's in the script. What do I have to do, make you have an awful day or something?
Wilt: No, no! I'll do it! I promise!

67 takes later...

Craig: GOD!
Bloo: *offstage* Ooooooooooooooooh, you said the "G" word!
Wilt: I'm SOOO sorry, I just can't seem to frown like that...
Craig: Bloo! You're not in this scene!
Bloo: But I got an IDEEEEAAAAA!!!
Craig: What is it then?
Bloo: Have Wilt think of the saddest moment in his life!
Craig: Hey, you know what? That'll work.

House of bloo's part 1

Craig:"Bloo meets Coco...Take 1!"

Coco:"Coco co cococo coco cococo co coco cococo co coco coco cococo!"
Craig:"Hey,Coco, stick to the script,okay?"

(In the style of Alan J. Back.)
Another one:

"The Big Cheese"--the imaginary friends bring Cheese to Foster's--take 1

(The blooper starts with the entire group of imaginary friends carrying Cheese and stopping in front of the porch.)
Mr. Herriman: All right. Now that Master Cheese is here...
Eduardo: (interrupting, concerned) Sr. McCracken, can we cut, please? I don't know if this feels right.
Craig: (coming in with Leonardo) What doesn't feel right, Ed? The episode or Cheese being the main character?
Eduardo: (still concerned) Neither one. If you want me to do a costume change inbetween scenes, I'll do it, (now confused) but don't make me go through all of it too much, okay? I don't know what side you're showing.
Craig: (laughing) I'm only doing it to make it funny.
Leonardo: Sí, hermanito. Try to do your best and follow along with the script.
Bloo: (coming in) Did I miss my cue?
Eduardo: (putting his right hand behind him, sweatdrop) Oh, right. Sorry. Maybe we should try that again, without me interrupting.
Craig: Right. (walking off camera) Can we take 2, people?
Eduardo: Uh, hermano mayor, you're not in this series, remember?
Leonardo: Oh, right. (catching up to Craig) Wait up, Sr. McCracken.
(The blooper ends.)

[Note: This would be the same behavior with one of the scenes of "Stewie Griffin: The Untold Story," only with a Foster's reaction.]

Mac Daddy-

Cheese: I liiiiike strawberry milk...

Craig: CUT! Cheese, it's chocolate milk, not strawberry!

Cheese: (in a British accent) Ah, my humblest apologizes, my dearest Craig. You see, as a young lad of four, I started to get this strange desire to drink strawberry milk all the time, and I never quite got over the odd addiction...

Craig: 0_o... Ooookaaay... TAKE 2!!


Yeah, I know it sucked, but that's all I can think of at the moment.

BWAHAHAHA. Cheese is actually a smart british friend who has to play as the stupid one. XDDD
