Hey, I heard you've never smiled once
Oooh
Never took you for a really big grump
Can't you smile once, dude?
There's no need to be so gruff
So rude
So my goal's to make you smile once (just once, just once)
Oooh

Oh, you-you may think that fun is stupid
Never even bump to funky music
Super stoic
Liven the mood, I'll make you lose it, lose it, lose it
I'll poke you all night, 'til your face is light
Mr. Frowny-Face Guy
Wanna see you smile, grim all the time
One little smile,
bet it looks nice

Put that knife down
Oooh
Why so serious, my man?
Your volatile reaction isn't cool
Need to learn to be calm
Before you can giggle, and I refuse, dude
To piss off, no, I will not stop til you laugh it up, bro
One little smirk, that's all I ask, though
With that frown, this'll take more than just jokes

Hey, I heard you've never smiled once
Oooh
Were you banned from jokes when you were still young?
That's just crazy, dude
You don't need to be stuck up
A douche
Now I've gotta make you smile once (just once, just once)
Oooh

G-G-Grumpy bastard or good actor?
I don't know
But I know I'll break ya
Man, your demeanour can't be good for ya
And the best medicine's laughter
It's true
I'll keep buggin' you til the sides
Of your mouth are raised up
Like the party's roof
Somehow, someway, gotta change your mood, mood
You're so stiff like you're made of wood
Uh-oh, maybe I'll put on a show
I can juggle lots of tomatoes
And if I make a mess, that just adds to the show
Ev'ryone loves slapstick, bro
You still look unfazed, maybe it's your tastes
Still look pissed, but two can play at this game
Alright, I'll just mimic you, bet your brain
Cannot handle this dumb face, c'mon, laugh, mate!

Hey, I heard you've never smiled once
Oooh
Man, there must be something that you find fun
Can't be this dull, dude
At this point, I can't give up
Won't lose
Yes, I have to make you smile once (just once, just once)
Oooh

I'll make you smile once, smirk or grin (yeah)
You will crack up then I will win (yeah)
I'll make you smile once, how 'bout now? (no?)
Bill Bailey stand-up didn't work, how?
A man who exudes comedy
Didn't make you giggle once, OMG
Take you to parties, absorb the vibes, all that bullshit stuff
But you still haven't smiled once

Hey, I heard you've never smiled once
Oooh
All my corny jokes, not even a punch
Give me a break, dude
Thwack on the head, I'll shut up
Weird truce
Maybe that'll make you smile once (just once, just once)
Oooh

Want you to smile once, please give in
If you find violence fun, I'll give
Deck me and smile once, I'd be proud
That you let loose for once, do it now
