BTW;; I plagiarized this entire thing!! Not to be confused with polygamy!!!
FACT: Prostitution helped kill the $2 bill. In the early 1900s, when the government was still trying to push the $2 bill (aka the American Toonie), the going rate for a prostitute was, coincidentally enough, $2 a night. (These days, you can still find deals like that, but you'd better have a raging stretch mark fetish.)
Eventually, $2 bills became associated with prostitution... so guys who were carrying them were roped in as johns, whether fairly or not. It's kind of like today when an athlete decided to go to USC, we assume he's making a great salary there, whether it's true or not.
