A bloke goes to the doctors as he's a bit uncomfortable "downstairs" The doctor has a look and says "well, you've made medical history you have three testicles" The bloke is overjoyed, he gets on the bus and says to the bloke next to him "I bet you £50 we've got five bollocks between us" The other bloke opens his flies and said "OK, here's my one, where's your four?"
