Poison Ivy

Poison ivy, poison ivy
Well late at night when you're sleeping
Poison ivy comes a creeping all around
Measles make you bumpy and mumps'll make you lumpy
And chicken pox'll make you jump and twitch
A common cold'll cool you and whooping cough'll fool you
But poison ivy's gonna make you itch

The Coasters

Not sure that it's poisonous but best I could come up with today as weather is still awful and couldn't go far. It was this or another blip of the dogs.
