As a child, this one-line song was performed every time I had finished a number two, prompting my father to come into the bathroom and wipe my arse. This is normal for small children, of course, but I got used to this luxury and opted-out of doing the deed myself probably for longer than I should have.
Eventually my patient father encouraged me to get on in life, fend for myself and embrace the defecation related hygiene that came with it. In time, I had almost forgotten about my brown jingle.
That was until I reached comprehensive. I'll never forget the mix of shame and fear I felt hearing my older brother and his gang of rough bully-boys yelling 'Da-dee I have Fi-niiiiiished' across a packed playground on my first day.
