Would-be bomber's undies failed to explode

Sewn into the underpants of would be plane bomber Umar Farouk Abdulmutallab was 80 grams of highly explosive PETN - photo and more info here. There will now be a rash of explosive underwear jokes - is that a bomb in your jocks or are you just glad to see me?

Anyway, it's a real shame the bomb didn't partially explode; you know, just enough to blow the Islamonutters dangly bits into heaven without him - those 72 virgins would no doubt have a good laugh. That would have discouraged any such future attempts.
