Dumb guy joke

A guy is having a drink in a very dark bar. He leans over to the big woman next to him and says, "Do you wanna hear a funny blonde joke?"

The big woman replies, "Well, before you tell that joke, you should know something. I'm blonde, six feet tall, 13 stone, and I'm a professional triathlete and bodybuilder. The blonde woman sitting next to me is 6'2", weighs 14 stone, and she's an ex-professional wrestler. Next to her is a blonde who's 6'5", weighs 15 stone, and she's a current professional kick boxer. Now, do you still want to tell that blonde joke?"

The guy thinks about it a second and says, "No, not if I'm going to have to explain it three times."
