When they don't have a catchphrase of their own, some characters happen to inspire them.
Indeed, a "phrase catcher" is someone whose sole presence is enough to inspire the same (or almost the same) verbal reaction among a various group of people. It works quite the same as a catchphrase except that the character doesn't say it but has it said about him... or her... or them.
Which of these movie/TV phrase catchers is the most memorable?
To be included, the 'catchphrase' must come from different characters, at least two, throughout the movie or the TV series (so no "Shut the **** up, Donny") and shouldn't introduce or come after another catchphrase from the protagonist (so no "Hi, Dr. Nick!")
