Two guys in a bar are discussing "positions" so one tells the other, "Well my favorite is the rodeo!"

and the other says, "What's the rodeo?"

"well, first you get your wife down and start to do her doggy style, then when you're halfway done, you bend over and whisper in her ear, 'you know, this is your sister's favorite position too' and then try to hold on for 8 seconds!"

Later, QD.
