Thats what she said

I know we have all said this at one time or another, its still used pretty frequently and made more popular by the show, The Office

i actually thought gerry might have invented this back in high school.

this was first said in 1992 in the movie Wayne's World by Mike Myers.

garth is holding up a pic of a girl while wayne talks about her on their show

Garth: “Hey are you through yet? Cause I’m getting tired of holding this.”
Wayne: “That’s what she said.”
