I'm not grumpy, I-I'm not grumpy
I-I'm not, I'm not (trust me), I'm not, I'm not

I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (yeah)
Gru-grumpy I'm not, gru-grumpy I'm not (I swear, shut up)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (yeah)
Gru-grumpy I'm not (yeah), gru-grumpy I'm not (I swear, shut up) (ooh-whoo!)

Don't have stored-up problems, nothin' I'm bottlin', that's nuts
My words aren't grumbles, I'm expressin' 'em clearly, shut it up
All your claims about me may be just a bit out there
The way I slam the door is not because life is not fair (ow!)
Steps are a bit louder than my more standard clip
Not stompin' at all, twit
Yeah, the way my feet fall have made all you dopes
Think that I'm pissed off, sorry, that's a "no" (yeah)
Even how I tap on my keyboard has
All you asses think that I have big issues, ain't a fact
"Bastard piece of crap!" Always been sayin' that
Y'all never wished to whack this printer 'til it cracks (ooh, ooh)?
I'm just sayin', I've not switched to anger like y'all think
My problems, I have a lid on top of all of it
I'm more shocked that you've picked
Up on tics I've expressed the whole time, no dif', same shit (oh!)

I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (yeah)
Gru-grumpy I'm not, gru-grumpy I'm not (I swear, shut up)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (yeah)
Gru-grumpy I'm not (yeah), gru-grumpy I'm not (I swear, shut up)

Actin' shocked like it's new shit but it ain't new, though
Try to guess why I'm like this, maybe work too, dopes (whoo!)?
"I bet that his pen's broke" "Nah, I bet the 'net froze"
Spitballin', forgotten I can hear it all (oh!)
I know what I hate, man, it's when I'm the sane man
Corral a bunch of fools to get paid, damn (yeah)
"That's it! You're miffed at guys who are thick!"
Like hell, your thinkin's gone a bit backwards
You all noticed things were not good and might just be bad
When I first clocked in, can't be annoyed how y'all act
Before I saw it, man, how'd you not clock that?
Oh yeah, you're stupid, thought train is real spotty
Keep playin' guessin' games and not fetchin' my copies
"10 bucks says his neck's bad" "15 says the left nad"
Holy cow, still at this now?
Ha! Ha (hahahaha)! There must be a gas leak around (oh!)

I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (yeah)
Gru-grumpy I'm not, gru-grumpy I'm not (I swear, shut up)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (I, I'm chipper)
I-I'm not grumpy, grumpy I'm not (yeah)
Gru-grumpy I'm not (yeah), gru-grumpy I'm not (I swear, shut up)

Yeah, I'm not a grump 'cause that's not enough
I want to cut y'all with a large chainsaw
Shove your heads through the wall, yeah, ignore the door
We're seventh story, know that, more pain in store (I, I'm chipper)
Might've heard the refrain, it might seem
That somethin' here contradicts (I, I'm chipper)
I can feel murderous and happy
Sick of your "he angy" shtick (I, I'm chipper)
Go 'way (I, I'm chipper)
Far 'way (I, I'm chipper)
Go 'way (yeah)
Far 'way (I swear, shut up)
Go 'way (I, I'm chipper)
Far 'way (I, I'm chipper)
Go 'way (yeah)
Far 'way (yeah, I swear, shut up)

I-I'm not grumpy, grumpy I'm not (I'm livid at you prats)
I-I'm not grumpy, grumpy I'm not (work isn't a bar, man)
I-I'm not grumpy, grumpy I'm not (how have you guys)
Gru-grumpy I'm not, gru-grumpy I'm not (not been sacked? Yikes)
I-I'm not grumpy, grumpy I'm not (I'm the sole guy)
I-I'm not grumpy, grumpy I'm not (who really tries)
I-I'm not grumpy, grumpy I'm not (to do work, ain't right)
Gru-grumpy I'm not (yeah), gru-grumpy I'm not (best pray you'll make it to 5)

I, I'm chipper
I, I'm chipper
Yeah, yeah
