The little ditty that the Pogues sing, not mentioned in the liner notes of their CD, is quite appropriate for Halloween.

WORMS

The worms crawl in and the worms crawl out
The ones that crawl in
Are lean and thin
The ones that crawl out
Are fat and stout
Your eyes fall in
And your teeth fall out
Your brains come tumbling
Down your snout
Be merry, my friends, be merry!
