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
