A brunette in a bar leans over to the girl next to her and says, "Wanna hear a joke about a retarted blonde girl?"
The girl next to her replies, "Well, before you tell that joke you should know something. I'm 6' tall and 160 pounds and I'm a blonde. The girl sitting next to me is 6'2" tall, 180 pounds and she's a blonde, and the girl sitting next to her is 6'5", 280 pounds and she's a blonde, too. Now, do you still wanna tell that joke?"
The brunette says, "Nah. I don't wanna tell it if I'm gonna have to explain it 3 times
