A friend of mine permanently ruined 'Oh Boy' for me, now I couldn't tell you what the correct lyrics are, all I can sing is -
"All of my life I've been missing
Your left tit cos your right one's missing, oh boy..."

Recently I've been learning "My Johnny was a shoemaker", and in the last couple of weeks he's ended up with various careers, but has ended up thus
"My Johnny was a punk rocker,
And dearly he loved me,
My Johnny was a punk rocker,
And pogo'ed out to sea...."

An imagination is a dangerous thing to leave to it's own devices...
