Lance Murdock

Captain Lance Murdock is a professional stunt devil who broke every single bone in his body while doing his stunts.

History
He inspired Bart Simpson to become a daredevil and convinced him personally to jump over Springfield Gorge on a skateboard.

Murdock later reappeared to do a stunt at Las Vegas. Homer decided to volunteer, as Ned Flanders was unwilling to risk his life for the stunt. The stunt was for him to go through rings of fire, ice, and dog poo while unlocking a safe box combination. He ends up seriously injured due to Homer getting up before the stunt was completed (although apparently having survived, given the fact that the announcer said "He's all right!")

He was briefly seen on TV performing a stunt.

He was among the celebrities who had been photographed by Homer.

Non-canon
When Homer was breaking bad news to a woman about her husband over Springfield Gorge, when he told her the bad news, she fainted and fell into the gorge and landed on Murdock's motercycle that he was using doing a stunt, they both presumably died or were seriously injured because of the extra weight. Homer told his family the story and after Lisa asked if they made it and Homer replied 'No...Big Crash..Less said the better'.
