Firecracker in the ass causes all sorts of damage.
From the "duh" department:
Tori Anus says -- "Here's a horrendous story. This is one man who will never take pooping for granted again."
A firecracker accident which left a 26-year-old man incontinent and unable to have sex has prompted warnings from police and health authorities about imitating stunts from the cult prankster film Jackass.
The man suffered a fractured pelvis and severe burns to his genital area after a firecracker exploded between the cheeks of his buttocks.
The man suffered extensive injuries from the explosion and required emergency surgery. He now has a colostomy and a catheter, and is sexually dysfunctional. He will be assessed by a colorectal surgeon to determine whether his injuries can be corrected.
Dr McCurdie said he believed the man had stumbled while the firecracker was in his buttocks, and fell down on it.
"By virtue of the fact that the explosion was confined in an upward direction, it went up into his pelvis, blasted a great hole in the pelvis, ruptured the urethra, injured muscles in the floor of the pelvis which rendered him incontinent.
