Apologies for reviving a dead thread but I just joined and just found this via a Google search.
Some of my all time favorites:
"You're a moron! In addition to being a thief, you're also a moron!"
"I guarantee you, ON BYRD'S LIFE, that you never gave them any money!" (cue mock outraged look from Byrd)
"Is that a hard question? I've asked it now three times. My four-year-old grandson could give me an answer to that question, madam!"
"You tell me one bubbe meise, I find everything else you say to me suspect!"
"What a sad story. That's the saddest story I've heard since 'Bambi.'"
"That's not happening." (informing a litigant that part or all of the case will be dismissed, often after seeing it for the first time)
"In my American educational system, children who are disrupting the class should be plucked out and put in a special school for disruptive children, That's my Blueberry Rule."
"Don't say stupid things to me. If you say stupid things to me, it presupposes that I am stupid. I don't want anyone to think I'm stupid. Old, maybe; stupid, never."
(Almost singing) "YOU'RE GETTING THE HONDA!!! ... And then I'm going to go do something that I find interesting, because this is not it."
"I don't care if he drives the car on the property or if he drives the car ON PLUTO!"
