Need help with a movie quote, ASAP!

[Groo The Perverted]

Okay this is REALLY making me frustrated. lol

I was talking with a friend of mine on AIM and I sent him a link to a page I wanted him to see. And he was like "alright" and I said "don't say alright and not go, I know how you people are" and as soon as I hit send I was like "ahhhhhhhhhhh that wasn't right" so I immediately followed that up with "how racial?"

So when he obviously came back with the "YOU PEOPLE???"

I instinctively wrote a line I remember from some movie (comedy) and can't for the life of me remember it.

The line was something like this:

person 1: What the hell is wrong with you people?"

person 2: "You people? What the hell do you mean YOU people?"

Person 3: *suddenly very quiet* I ..I didn't mean YOU people...I meant....you know...you people"

and I can't remember what it's from. Not tropic Thunder and not Happy Gilmore (the only other movie I can recall with someone yelling "what the hell is wrong with you people?"

If someone can help me out I'd be VERY appreciative as this is gonna bug the hell out of me until I figure it out.

I tried google but got one forum that had it as a signature but no reference.
