Here's another version, which I learned one year in
summer camp:
Great big globs of greasy grimy gopher guts
Mutilated monkey meat, little dirty birdy feet
Fresh brewed eyeballs frying in a frying pan
But I forgot my spoon, so gimme a sandwhich
With pus on top, monkey vomit and camel snot
Fresh brewed eyeball, dipped in doo
Eat it
insert name of unpopular camper (sometimes me) here, it's good for you!
