McFly - Diarrhea lyrics 
When your climbing up a tree and [bad word] down your knee
Diarrhoea, Diarrhoea
When your sitting in the gutter and your eating bread and butter
Diarrhoea, Diarrhoea
When your climbing in the the loft and your tread in something soft
Diarrhoea, diarrhoea
It isn't very fun, when you've got [bad word] bum
Diarrhoea,Diarrhoea
When you're swimming in the ocean and you hear a big explosion 
Diarrhoea, diarrhoea
When [bad word] out your bum, like a bullet in a gum
Diarrhoea
Diarrhoea
Yeah,yeah,yeah
Diarrhoea
