I’m pretty sure this is a song lyric from “the poor”, by Jesse Welles.

“I was memorizing capitols

I was in the spelling bee

I must’ve missed the part

Where they taught the art of private equity

I was selling chocolate bars

I had a disorder

I was cuttin’ up a frog

Got lost in the fog

Learnin’ how to play a recorder

“

I don’t think it’s supposed to be a slam against musical instruments.
