(grunt)

Who are you lookin' at?!

There's a grump on your toe

And he doesn't wanna go (no)

That's called a grumpy boy

There's a grump on your calf (I'm not ticklish)

Tryin' not to laugh (chuckles, maybe just a little)

That's called a grumpy boy

There's a grump on your belly

He's all covered in jelly (oh, man)

That's called a grumpy boy (listen)

There's a grump on your collar

He's just about to holler (hey, who put on this music?)

That's my grumpy boy

All right grumpy boys, can you sing along?

Grumpy boy (grumpy boy)

Cheer up, cheer up, grumpy boy

But there's a grump in your hear (ahh!)

Cheer up, grumpy boy

There's a grump on your knees

She's gonna make you sneeze

That's called a grumpy girl

There's a grump on your head

She thinks that it's a bed

That's called a grumpy girl

There's a grump on your armpit, ooh!

Playin' on the trumpet

That's called a grumpy girl

There's a grump on your nose

There's a grump in the kitchen

Who's doin' the dirty dishes

And there's a grump in the shower

Who's been in there at least an hour

There's a grump who needs his coffee really bad

That's called a grumpy dad

And in case you're wondering

There is no such thing

As a grumpy mom

You didn't hear it from me, at least (chuckles). Right, but just for the sake of argument, let's see if we can get some moms to pretend that they're grumpy and sing along for this chorus. You ready, moms? Here we go!
