The one I heard was:There was a young lady called Horton
Who had one big long tit and a short 'un
To make up for that, she'd a fuckin' big twat
and a fart like a 650 Norton.
There was a young lady from Horton,
Who had a long tit and a short 'un,
To counteract that,
She had a lobsided twat,
And a fart like a 650 Norton.
