You're mean one Simon C.
You really are stoned hard
You're as evil as a beaver
You're not charming as an bard Simon C.
You're a bad crackpot full of greasy ol' lard

You're monster Simon C.
Your heart's an empty shoe
Your pants is full red ants
I vomit on your toes Simon C.
I wouldn't touch you if you were
Meaner than Moe

You're a vile one Simon C
You've got spinach in your smile
You have all the bad bitterness of an ugly crocodile Simon C
Given the choice between the both of you I'd take the a ugly crocodile

You're a creeper Simon C
You're the king of shameful puns
Your heart's a dead tomato, and glad that I ain't your son Simon C

Your soul is a appalling dump heap
Overflowing with the most disgraceful
Assortment of deplorable rubbish
Imaginable, mangled up in tangled up junk

You nauseate me, Simon C
With a nocuous super nose
You're a crooked cowfaced jockey and,
you drive an ugly horse Simon C

You're a 3 Deckered sour cheese and spam stall sandwich
With muriatic sauce!

You're a foul one Simon C
You're a nasty stinky skunk
Your heart is full of unwashed undies
Stacked up in a smell hunk Simon C

The 3 best words that best describe you, are as follows, and I quote
Simon, You, SUCK!
