Off hand, I can only remember a few:

"Shoot me now, shoot me now." Daffy Duck
"Game over." Aliens (yes Top, I believe we all use this one)
"Just put your lips together & blow". (no explanation needed)
"Frankly Scarlet..." everyone knows the rest of this one.

These are just a few that my Swiss cheese memory let's me think of right now. But I use many more. More than I realized until I married a lady from the other side of the world. I can't tell you how many times I have had to stop to explain something I said only to realize that it was a quote or reference to an old movie or cartoon that she's never seen. Mostly it turns out to be from old Disney movies.
