While at work one day, a young man had a nasty accident and lost his todger in a press, meaning it was too badly damaged to be re-attached.
"Not to worry," said the attending surgeon: "I've spoken with various male members of your family and they've all agreed to donate and inch each, which, using modern medical science can be joined together and grafted to your vacant groin."
Well the surgery was successful and the young man was discharged from hospital a few days later, with the instruction to come back in six weeks for a checkup.... which he attended without fail.
"So," asked the sugeon: "how is it all going?"
"Not so bad, doc," replied the young man: "though occasionally I suffer with incontinence."
"Ah yes, that would be due to the bit from your grandad." said the surgeon: "but other than that, have you any other problems, like urination, for example?"
"Oh no, doc," replied the young man: "I'm pissing like a trooper!"
"That's good, very good, in fact! Any other issues to mention?"
"Come to think of it, which I do, now that you mention it, I do have a problem when I get aroused and want to make love to my wife.... you went and put grandad's bit in the middle."
