Bill Cosby's Second Date

Listen here, my friend, you ain't the sharpest tool in the shed. The joke is about Bill Cosby, who was accused of drugging women and sexually assaulting them. So, when he says "Hi, nice to meet you" on the second date, it implies he doesn't remember the first date because he drugged the woman. Which is a dark reference to the allegations against him. Get it now, blockhead?
