Joe Biden's recent "big f**king deal" gaffe on live television is raking in dough for the Democratic Party ... all in the form of an awesome, slightly inappropriate $25 t-shirt.
The shirt -- sold on BarackObama.com -- is real, we promise ... and the Democratic National Committee is behind it.
It even has the date March 23, 2010 on it -- the day Obama signed the health care reform bill and Joe Biden effed up on live television.
That's a change of clothes you can believe in.
