Actually, it's just a silly homage to green jello the food. I wrote the poem in college and Green Jello was served 5 out of 7 nights a week at the Caf.
Green Jello does suck but in a hilariously entertaining way. My dear wife bought me the Cereal Killer video off of Ebay, though she refuses to watch it with me. That and the Smurfs and the Magic Flute.
