It's not just a dollar, it's a dollar maybe... This would be 2 hard ups working together. The one doing it is hard up for a dollar and the one getting it done can only afford a dollar, maybe.
I went to high school with a guy that would do anything for a dollar. I had him walk up to a chick and dump a bag of M&Ms down her pants because her butt crack was showing. Got him to walk up to 2 fat chicks sitting down, pull his pants down enough where his ass was showing, turn around to them and carry on a 2 minute conversation using his butt like a puppet. Fun times....
