Oh Wally, lead us not into temptation!

whennnnnnnnaaaa
hungry apod
chews a piece of your bod
that's-a moray!

when a no pelvic fin
digs right in to your shin
that's-a moray!

when an ell eats your heel
and he calls it a meal
that's-a moray!

when a long skinny fish
eyes your ear as a dish
that's-a moray!

Dean Martin sings...

When an eel bites your toe,
And he won't let it go,
That's.... a moray...
