One day, a deaf mute walks into a Chemist to buy some condoms. He has
difficulty communicating with pharmacist, and cannot see condoms on the
shelf.
Frustrated, the deaf-mute finally unzips his pants, places his willy on the counter, and puts down a five-pound note next to it.
The pharmacist unzips his pants, does the same as the deaf-mute, and then picks up both notes and stuffs them in his pocket.
Exasperated, the deaf mute begins to curse the pharmacist wildly in sign language.
"Look," the pharmacist says, "if you can't afford to lose, you shouldn't make a bet..."
