Reminds me of an old dirty joke.
Guy is dissatisfied with the size of his penis. He goes to see about surgery to have it lengthened. The doctor tells him, "We have an experimental procedure you might be interested in, where we actually graft in a few inches of baby elephant trunk." The guy decides to go for it, and 4 months of convalescence later, he thinks he's ready to "try it out in the field."
He invites a female acquaintance of his to dinner, and everything is going well. Then, suddenly, his member - which had up until that point been resting comfortably in his pants leg, shoots up above the tablecloth, grabs a roll out of the breadbasket, then disappears back under the table.
The lady is impressed. "Do that again!" she says.
"Well, ok..." he says, "but... I'm not sure my ass can take another hard roll."
