McFly - Diarrhea lyrics When your climbing up a tree and it's running 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 a runny bum Diarrhoea,Diarrhoea When you're swimming in the ocean and you hear a big explosion Diarrhoea, diarrhoea When it's coming out your bum, like a bullet in a gum Diarrhoea Diarrhoea Yeah,yeah,yeah Diarrhoea
