Billy Kelly

Billy Kelly`s belly
Troubled him a lot
For just above his navel
Was a massive yellow spot

When sunbathing or swimming
He suffered vile abuse

His legs and feet turned green
He hung around street corners
Determined to be seen

Of symptoms such as these
Poor Billy is a victim of......................
