A bloke loses his manhood in an industrial accident and the treating surgeon gave him the bad news that it was too badly damaged to be reattached. "However," the doctor says: " a baby elephant died prematurely at the zoo and I can graft on a piece of its trunk to replace your missing willy."
"Okay," the bloke replies: "anything has to be better than no willy at all."
With that the surgeon proceeds with the grafting and it was a resounding success, so when the bloke is ready to leave the hospital the doctor asks him to return in a months time for a post-op checkup. At the checkup the doctor examines his handy work and declares that it is a marvel of modern medicine. He then asks the bloke how he's handling the new 'equipment.
"Well," the bloke responds: "When I used to go to the toilet it was slow and it often dribbled, but now, with this new willy, I piss like a brewer's horse. And the sex, well my wife loves it and it performs magnificently. There was one problem, though."
The doctor asked him what that was. The bloke says: "Well I took my youngster to the zoo last Saturday, and when we were standing at the elephant enclosure it burst out of my trousers, grabbed a handful of peanuts and shoved 'em up me arse"
