A guy can't obtain an erection so he goes to the doctor. The doctor tells him the muscles at the base of his penis are broken down and there's nothing he can do unless he's willing to try an experimental surgery. The guy asks what the surgery is. The doctor tells him they take the muscles from the base of a baby elephants trunk, insert them in the base of his penis, and hope for the best. The guy says that sounds pretty scary but the thought of never having sex again is even scarier so go ahead. The doctor goes ahead and performs the surgery and about 6 weeks later gives him the go ahead to "try out his new equipment". The guy takes his girlfriend out to dinner. While at dinner he starts feeling an incredible pressure in his pants. It gets incredibly unbearable and he figures no one can see him so he undoes his pants. No sooner does he do this than his penis pops out of his pants, rolls across the table, grabs a dinner roll, and disappears back into his pants. His girlfriend sits in shock for a few moments, then gets a sly look on her face. She says "That was pretty cool! Can you do that again?" With his eyes watering and a painful expression on his face, he says

"Probably, but I don't know if I can fit another dinner roll up my ass!".
