How do you sex a wombat....That reminds me of the story of the feller visiting a friend. They was a'settin' on the porch when this dog laid down out in the yard and commenced to reach back and lick on his private parts. The feller said to his friend, 'Boy I sure wish I could do that!" To which his friend replied,"Well,....if'n ya scratch him for while behind his ears first, he may let ya!"
