Just to start the thread while I try to think of others, one I enjoy finding an occasion to use is one I heard on the old Johnny Carson show courtesy of Jimmy Dean (the sausage king).
“I don’t understand it, I just don’t understand it: every time I get out of jail, it rains.”
“hey HEY hey!” from the late '70’s TV show “What’s Happening”. I’ve used it as a greeting so often and for so long many of my friends now associate it with me (or me with it, or something).
Said to myself or coworkers when someone effs up. It comes from that Far Side cartoon with the man saying to his dog “You call that mowing the lawn? Bad dog! No biscuit! No biscuit!”
The link to 10 movie catchphrases includes “there’s no place like home,” from the Wizard of Oz.
Actually the phrase comes from a song of the same name TNPLH, written in 1822. Most people when the movie was released would have recognized it. You missed “the devil made me do it”,
“whatch you talkin’ about Willis” “goodnight Mrs. Calabash, where-ever you are”“Hi Ho Silver, away!”
