Care of How I Met Your Mother:
Barney: [To Ted] Do you have some puritanical hang up on prostitution? Dude, it’s the world’s oldest profession.
Marshall: Do you really think that’s true?
Barney: Oh yeah, I bet even Cro-Magnons used to give cave hookers an extra fish for putting out.
Marshall: Ah ha, so the oldest profession would be fishermen. Kaboom! You’ve been lawyered!
Barney: That’s adorable Ted. You’re such a hayseed. The companionship business is the growth industry of the 21st century. You do realize that 1 out of every 8 adult women in America is a prostitute.
Marshall: Dude you just made that up.
