There are so many classic catchphrases in the history of TV that nobody could possibly collect them all.  But somebody put together a pretty impressive YouTube montage of a lot of the best ones.

 

It's five minutes long, and includes stuff like "What'choo Talkin' 'Bout Willis" from "Diff'rent Strokes", "Bazinga" from "Big Bang Theory", "That's What She Said" from "The Office" and "Marcia, Marcia Marcia" from "The Brady Bunch".

 

 WARNING:  It includes a few B-WORDS.
