Jack goes to the doctor and says "Doc I'm having trouble getting my penis erect, can you help me?"
After a complete examination the doctor tells Jack, "Well the problem is that the muscles around the base of your penis are damaged. There's really nothing I can do for you unless you're willing to try an experimental treatment."
Jack asks sadly, "And that would be?"
"Well," the Doctor explains, "What we would do is take the muscles from the trunk of a baby elephant and implant them in your penis."
Jack thinks about it silently then says, "Well the thought of going through life without ever having sex again is too much, let's go for it."
Jack went under the knife, and, after a period of recovery and healing, returned to the Doc for his blessing. Following the examination, the Doc pronounced Jack "healed and ready for action".
Eager to use his experimentally enhanced equipment, Jack planned a romantic evening for his girlfriend and took her to one of the nicest restaurants in town, anticipating a happy conclusion to the evening.
In the middle of dinner he felt a stirring between his legs that continued to the point of being painful.
To release the pressure, Jack placed his napkin on his lap and unzipped his fly. His penis immediately sprung from his pants, flipped the napkin on the floor, went to the top of the table, grabbed a bread roll and then returned to his pants!
His girlfriend was stunned at first but then, imagining the possibilities, said with a sly smile and a gleam in her eye, "That was incredible! Can you do it again?"
Jack groaned, "Probably, but I don't think I can fit another roll in my ass."
