Something happened when I lit a cigarette in an oxygen tent.
I'll tell you what happened instead of just giving you a hint.
That oxygen tent went up in flames and I got burned all over.
I learned that it doesn't bring good luck to have a four leaf clover.
I've got burns all over my body, even my privates were burned.
Oxygen and lit cigarettes don't mix, that's something I learned.

(This is a fictional poem)
