An old man and woman had been seeing each other quite a bit, and well, they weren't getting any younger so they decided to go ahead and get married. On their wedding night they decided that they may as well consumate the thing so the old man starts to get undressed. He takes off his shoes and the woman sees that he has a toe missing.
She asks about it and he say, "When I was younger I had tolio". She says, "You mean Polio..."
He snaps back, "No I mean Tolio damnit!" Then he takes off his trousers and she sees that his knees are disfigured as all get out.
She asks what happened and he replies, "When I was younger I had Kneebola" She says, "Ebola?"
He says, "Damnit woman are you deaf? I said Kneebola!" Finally he takes off his underwear and she says, "Oh great, KNOW you're going to tell me you had small cox..."
