A Malaysian welder had to have a nut removed from around his penis after an attempt to lengthen it before he gets engaged next week went embarrassingly wrong, a news report said Sunday.

The nut got stuck on his penis following an erection, the Star newspaper said, forcing him to seek help at a hospital in southern Johor state.

Staff from the Sultanah Aminah hospital had to drain some blood from the penis and cut away a top layer of skin before the object could be removed, the newspaper said.

It said the fire and rescue department were also involved in trying to remove the nut from the unnamed welder, who is in his 20s and hoped the nut would weigh down his penis to make it longer.
