Two rednecks, Jake and Bubba, were walking through a pasture.
Jake sees a sheep caught up in a fence and says to Bubba “I’m gonna get me some of that”!
Jake goes over and sticks the sheep’s back feet in his rubber boots, unzips his pants and starts to have sex with the sheep.
He looks over his shoulder at Bubba and says “Do you want some of this”?
Bubba replies “yes let me see if I can get my shirt caught up in the fence”.
