Name that Movie!

Ah yes, another version. I had a different title for the post but that would have given it away too quickly. Anyway, this movie popped into my head this afternoon for no good reason. Well, actually there was a reason, but if I say it or link to it, it would be far too easy also.

Anyhoo, identify one of the funniest movies I've ever seen:

"I know what you're thinking... and you ought to be ashamed of yourself."

"There's nothing more inconvenient than an old queen with a head cold."

"Who the hell does he think he is?"
"The French middle weight boxing champ. But don't worry, he's gay."

"What will you have?"
[pause] "Milk."
"Cow's milk, monsier? Or mother's milk?"
"How about your sister's."

And if you haven't gotten it from the gimmes above, here's the one I considered using for the post title:

"COCKROACH!"
