A charming blonde goes into a bar and sits down next to a very dumb guy.
Suddenly she strikes up a conversation with him and soon they become rather chummy.
It starts to get late and the bartender calls out for the last drink for alcohol, then the blonde leans over to the guy and says, “Let’s have this last drink at my apartment. “
The guy agrees and they headed for the door, when the blonde stops him and says,
“Before we go back to my apartment there’s one thing I have to tell you, I’m on my menstrual cycle. “
He says,
“That’s ok, I’ll follow you in my Harley. “
