A Sordid Soirée

You fearfully descend into the lair
and discover a strange glistening trail
then see the eyeball bouncing down the stairs.
Your host gives you a salad, with a nail,

yellow, and still attached to the cold toe.
What else lies beneath limp lettuce leaves?
You try the soup but would much rather go.
You can see your host's head hopping with fleas.

In the soup you notice a floating scab.
You ask your host, What type of soup is this?
He says, I concocted it in my lab!
His answer you do try hard to dismiss,

but when the live cockroach falls from his hair,
you can't stop yourself, and run from the lair.
