Magnetic Poetry gone horribly wrong

I walked into the study hall that I help out in today (at the high school), and the teacher was putting magnetic poetry words on the side of the file cabinet. I got all excited, and immediately went to work and wrote a poem.

gentle child we ride with joy
music inside
glow warm morning
imagine
truth
know magic
understand peace
share
whispers
play with your world

When the kids came in, they looked at it and one guy said, "Who wrote that stupid poem?" or something like that. The teacher came in and said that if they wrote anything dirty on there, it would be gone. So they immediately set to work, destroying my poem in the process.

"You can't make anything dirty out of those words," I said. "It's a kids poetry set."
Naturally, being teenage boys, they came up with a few sentences that were not very nice. So I made them pick them apart and find the subjects, the verbs, direct objects and prepositional phrases.
Then they came up with this:

The black boy had a snake in the teacher's garden.

Then they started to make several racist comments. I started to get angry. I said, "You know, when I'm around you guys, I feel very discouraged about the human race."

One kid looked at me. "Huh?"

Exactly.
