Another Buddy Holly one -

All my life, I've been akissing
Your left tit cos your right one's missing....

And a Jasper Carrott one, guaranteed to have them heaving in the aisles:

I'm just wild about acne, acne grows wild about me,
I'm just covered in gurgling zits, as far as the eye can see;
They call me Mellow Yellow....

I'll get me coat....
