A bloke goes into a bar and somebody is selling a toothless ferret.

"What use is that"?, he asks, "That's not going to catch many rabbits".

"Slip it in it your trousers" the seller replies.

So he puts it down his pants it gives him the best BJ ever. So he buys it, takes it home and gives it to his wife

"Oh" she says "Whats this"?
The bloke replies "It's a toothless ferret".

"What am I going to do with a toothless ferret"? she asks.
"Teach it how to wash up then pack your bags and fuck off"!
