I am so lowbrow:
Grandma: Sir, can I trouble you for a warm glass of milk? It helps me go to sleep.
The Nursing Home Orderly: You can trouble me for a warm glass of shut-the-hell-up! Now, you will go to sleep or I will put you to sleep. You're in my world now, grandma.
and
Shooter McGavern: I eat pieces of shit like you for breakfast.
Happy Gilmore: You eat pieces of shit for breakfast?!
and of course the best of all is the one from Billy Madison:
Mr. Madison, what you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.
