Never hold it in

Dr. Michael Levitt, a Minneapolis gastroenterologist who is probably the world's leading expert on flatulence, tells of a somewhat gassy patient who was having a rectal polyp cauterized one day and unexpectedly exploded on the operating table.

No fooling. An electric spark caused the hydrogen in the patient's bowels to detonate, blasting the surgeon backwards against the wall and slamming the patient's head into the table. The explosion also ripped a six-inch hole in the patient's large intestine. Luckily, they were able to sew him up OK and the poor guy recovered.
