A guy in a bar leans over to the guy next to him and says, "Wanna hear a Beaver joke?" The guy replies, "Well, before you tell that joke, you should know something. I am 6' tall, 200 lbs. and I am an OS(U) graduate. The guy sitting next to me is 6'2", 225 lbs. and he is an OS(U). The guy right next to him is 6'5", 250lbs. and he is also an OS(U). Now, you still wanna tell me that joke?"
The first guy says, "No, not if I'm going to have to explain it three times"
