Rodeo....

Rodeo  Two blokes are having a beer, talking about various sex positions. The first bloke says that his favorite position is the "rodeo." The other bloke asks what the position is and how to do it. The first replies, "Well, get your wife on all fours and do it doggy style. Once things get underway and she's really enjoying it, lean forward and whisper in her ear, 'Your sister likes this position as well.' Then try and hang on for 8 seconds."
