[Verse 1: Rhett]:
So you've saved a little room for dessert (yeah)
Not really but a little dessert won't hurt (nah)
But wouldn't you know a BOGO promo (oh)
On double mint chocolate chip cookie dough (oh)
Before your mom pulls the car around (yeah)
You already popped the lid and scarfed it down (mmm)
Pace yourself, brother
Your mouth's writing checks that its roof can't cover

[Chorus: All]
You're gonna get an ice cream headache
Owwww!
You're gonna freeze your brain
No way to ease the pain
You're gonna have to wait it out
You've got an ice cream headache
Nowwwwwww!
You're the one to blame
So you can't complain
You ate it like a Grizzly downin' a rainbow trout
He's really ravaging on that trout

[Verse 2: Rhett and Link]
You look like you've been kicked in the balls (oaahh)
But that ain't happening at all (nah)
Let me simplify things for ya
You see your Trigeminal Nerve is causing sphenopalatine ganglioneuralgia
[Chorus: All]
A.K.A. an ice cream headache
Owwww!
You're gonna freeze your brain
No way to ease the pain
You're gonna have to wait it out
You've got an ice cream headache
Nowwww!
You're the one to blame
So you can't complain
You ate it like a screech owl pecking the life out of a mouse
Like a pack of dingos tearing up a dairy cow
I bet you wish you were lactose intolerant now
