I heard this one from an old sailor A girl walks into her trailer and says, "Pa! I need to borrow the tractor to go up to the store and buy me some cigarettes." Her Pa says, "Alright, but you gonna have to work for it." "What do I have to do," asked the girl. "You gonna have to blow me if you want that tractor." "Alright Pa," says the girl. The girl starts sucking her Pa's dick. A second later she say, "Ew Pa, your dick taste like shit!" Her Pa replies, "Sorry, your brother borrowed the tractor this morning."
