Well, well, well, well... 
Now, let me tell you a story 
About someone who despises the holidays! 
He's mean and he's green, ooh... 
Now listen up 

You're a mean one, Mister Grinch 
You really are a heel 
You're as cuddly as a cactus, you're as charming as an eel, Mister Grinch! 

You're a bad banana with a greasy black peel 

You're a monster, Mister Grinch 
Your heart's an empty hole 
Your brain is full of spiders, you've got garlic in your soul, Mister Grinch! 

I wouldn't wanna have to touch you with a thirty-nine and a half foot pole 
Woah, no-no! Keep him far, far away from me now! 

You're a vile one, Mister Grinch 
You have termites in your smile 
You have all the tender sweetness of a seasick crocodile, Mister Grinch! 

Given the choice between the two of you, well I'm gonna have to take the seasick crocodile 
Tick-tock, tick-tock, watch out for the big bad croc now! Ha, ha, ha... 

You're a foul one, Mister Grinch 
You're a nasty, wasty skunk 
Your heart is full of unwashed socks, your soul is full of gunk, Mister Grinch! 

The three words that best describe you are as follows, and I quote 
"Stink! Stank! Stunk!" 

You're a rotter, Mister Grinch 
You're the king of sinful sots 
Your heart's a dead tomato splotched with moldy purple spots, Mister Grinch! 

Your soul is an appalling dump heap overflowing 
With the most disgraceful assortment of deplorable rubbish imaginable 
Mangled up in tangled up knots 
Oh, let's go! 

You nauseate me, Mister Grinch 
With a nauseous super naus 
You're a crooked, jerky jocky and you drive a crooked hoss, Mister Grinch! 

You're a three decker sauerkraut and toadstool sandwich, with arsenic sauce!
