think before you do that my friend
when i was still working in the hospital i got talking to this guy, had been pretty badly smashed up in a motorbike accident,after numerous operations he was home but still needed extensive surgery. he was fairly philosophical about it all but said he always remembered a guy who was in the same ward as him when he first crashed the bike. the guy had completely snapped ligaments in his knee and was in agony. they got talking and he asked him how he did it,expecting to be regaled with tales of a football related injury, instead he got a massive shock when the guy told him he had been biting his toe nails (yes,foot in mouth) and heard a snap before he passed out
the moral of the story is, if you snap ligaments while your foot is in your mouth eating your toenails.....never,ever admit it
