Two guys are talking over a beer, discussing various sex position. The first guy says his favorite position is the "rodeo". The other guy asks what the position is, and how to do it?

The first guy says, "You tell your wife to get on the bed on all fours and then do it doggy style. Once things start to get underway and she's really enjoying it, lean forward and whisper in her ear -'Your sister likes this position too'... Then try to hang on for 8 seconds."
