Lyrics
Today’s just so wonderful, I feel like chuckling Ha ha ha
I feel all fuzzy inside like a duckling; full of tarantulas And now that I’m here, tonight, it’s gonna get weird!
Ah-ha-ha-ha!
Look at these creatures, not enough features Cats should breath fire, bears should sing choir! *Choir singing* (Very nice)
Look at this tower under my power Look at these people, puny and feeble!
(Ooooooo hoooo!)
Look, I’m just a triangle trying to save you From the delusions society gave you
Gravity’s a lie and so is the sky Trust in the all-seeing, all-knowing eye!
Look at this money–who’s that, honey? Look throughout history, how could you miss me?
(Seriously, I’m all over the place)
Look at this weather, I could do better Mandelbrot rainbows, screaming tornadoes!
Look at this loser, drinking coffee *Sips* …Now it’s decaf! *Spits*
(Mwahahahaha!)
Look at these people, calling me evil Right back at you, now you’re all statues!
Now everything you know has disappeared It’s gonna get weird...
