You're a mean one, Mr.Grinch
You really are a heel
You're as cuddly as a cactus
You're as charming as an eel, Mr.Grinch
You're a bad banana with a greasy black peel

You're a monster, Mr.Grinch
Your heart's an empty hole
Your brain is full of spiders
You've got garlic in your soul, Mr. Grinch
I wouldn't touch you with a 39 and a half foot pole

You're a foul one, Mr.Grinch
You have termites in your smile
You have all the tender sweetness of a seasick crocodile, Mr.Grinch
Given the choice between the two of you,
I'd take the seasick crocodile

You're a foul one, Mr.Grinch
You're a nasty wastey skunk
Your heart is full of unwashed socks, your soul is full of gunk, Mr. Grinch
The three words that best describe you are as follows, and I quote
Stink! Stank! Stunk! 

You're a rotter Mr.Grinch
You're the king of sinful sacks
Your heart's a dead tomato splotched with moldy purple spots, Mr. Grinch
Your sole is a appalling dump heap 
Overflowing with the most disgraceful
Assortment of deplorable rubbish
Imaginable, mangled up in tangled up knots

You nauseate me, Mr. Grinch
With a nauseous super 'naus'
You're a crooked dirty jockey and you drive a crooked Hoss, Mr. Grinch
You're a three-decker saurkraut and toadstool sandwich
With arsenic sauce
