Can't hide that grin, I can see
That you are laughing at me
It's so clear how you try to keep your feelings bottled up
Don't prolong the farce, let it out before you get punched

I can tell that your face is twitching rapidly
Won't look in my eyes without a short wheeze
I'm no fool, I can see, you're not being real stealthy
Can't hide that grin

I see your lip quiver, you're not sad, please
The veneer has cracked, I know what I see
So you're just fooling yourself, your whole plan has failed
Obvious it hurts, so please exhale

So many tics in your face that anyone can see
Yes, even if blind, they can hear the wheeze
You're not fooling me, see, something is real damn funny
Can't hide that grin

You haven't hidden jack, mate, so cut it out now, please
And just tell me why you find me funny
I'm no fool, I can see (I'm no fool, I can see)
Can't hide that grin
You're not fooling me, see (you're not fooling me, see)
You can't hide that grin
I'm no fool, I can see (I'm no fool, I can see)
Can't hide that grin
You're not fooling me, see (you're not fooling me, see)
Can't hide that grin

I'm not fooled, can't hide that grin
Can't hide that grin
I'm not fooled, can't hide that grin
I'm not fooled
