Two Texans were out on the range talking about their favorite sex positions.

One said, 'I think I enjoy the rodeo position the best.'

'I don't think I have ever heard of that one,' said the other cowboy. 'What is it?'

'Well, it's where you get your wife down on all fours and you mount her from behind. Then you reach around and cup each one of her breasts in your hands and whisper in her ear, 'Boy, these feel just like your sister's.'

Then you try and stay on for 8 seconds.
