"The Eggplant That Ate Chicago" was recorded by Dr. West's Medicine Show and Junk Band. It was written by Norman Greenbaum who later had a big hit with "Spirit in the Sky" and I'm Casey Kasem.

The Eggplant that Ate Chicago

(chorus)
You better watch out for the eggplant that ate Chicago
For he might eat your city soon
You better watch out for the eggplant that ate Chicago
If he's still hungry the whole country's doomed

He came from outer space lookin for something to eat
He landed in chicago he thought Chicago was a treat
(it was sweet, it was just like sugar)

chorus

break

repeat verse and chorus

If you have any specific requests let me know. I know a lot of legitimate jug band songs as well as much silly drivel from the 60's.
