One day a redneck farmer goes to farmers market and asks "Do you have any donkeys" 

"Yes, but we call them asses" the man replies. 

"Ok, I'll take one" says the farmer "also I need a rooster, have you got any" 

"No" replies the man "but we do have some cockrells. Will that do." 

"Sure" says the man "Gimme one of those also" 

When he arrived home he found that both his new animals were being quite troublesome. 

He called his wife and said "You bend down and grab my cock, while I slap my ass"
