Dumb and Dumber?
Heck, one more…
“I hope you didn’t go to any trouble on my account. I’m not gonna break the door down. I’m just gonna give you a little time - to try to be reasonable. If you decide you’re not gonna be reasonable, then, one night, when you come home, you’ll find me on the inside, waiting for you. And that’ll be the night you’ll wish you’d never been born.”
Never saw the film, so far all I know that could have been said in that flick, but I’m thinking about a different film.
Wayne’s World?
Another film I didn’t see. (I must not have a life, I guess) Will have to say no again even if that phrase was said in WW.
At least you’re on the right track of screwball comedies.
Pee-Wee’s Big Adventure?
The only other one I can think of right now is The Blues Brothers.
Nope. Final hint (hoping not have gone there, but) - my current avatar.
Animal House.
Got it! 
I knew I recognized that face (It’s Dean Wormer’s!) from someplace other than Mission: Impossible (the TV series).
From the same movie:
“Sure, steak is great, but why would you want that all the time when you can try duck?”
“You got a business to run here, and the last thing you need, especially this week, is a dead guy in your lobby. But hell, seeing as you got one, I think I’ll take a look around, ask a few questions, you know, do the whole cop thing.”
Oh, that’s not right!
Sounds like Eddie Murphy in Beverly Hills Cop or BHC2.
Nobody has correctly guessed my most recent contribution yet.
Galaxy Quest.
‘I said it looked clear.’
Did anyone guess Real Genius yet?
Since I don’t think anyone is going to get this one.
I was watching a movie the other day and I had an idea for a variation on this thread. How about quotes from a movie you can figure out even if you haven’t seen the movie.
“Ten oughta do it, don’t you think?”
Still nope.
Too easy…Ocean’s Eleven
