My Mentally Unstable Classmate

I have a classmate
His name Finn

(He doesn't actually have Down Syndrome, but insist that he does.)

I saw him at the local Plaid Pantry (was it Jim's Market?)
And the thing that he did
Made my mouth drop open
When he shoved a kid,
Into a white van
With a whip in his hand
And a very large bag with the words
"Big Boi Sand" written in large Comic Sans

His van had tinted windows,
The license plate said R A (and ended with) P.E
And on the side of the car, it freaking said
"****ing Grapes with Glee"
He's mentally unstable
Some say he should be locked up
But as long as he's thinking of Quandale Dingle
He'll get out by calling "GOOFY AHAH!!!"

So I have a classmate
His names is Finn
And he's the most unearthly person there's ever been...
