Big Cheese

The class will soon know
What I've had for lunch.
I can feel it building;
Ready for a trumpetous blast.

I'm squeezing tightly
Trying to hold it in.
Won't last much longer;
Too much time is left!

The teacher sits at her desk.
The room is filled with silence.
My colon is ready to burst;
Why did I choose burritos?

Giving up, I lean to one side.
Closing my eyes, saying my prayers,
I let 'er rip at full blast.
I think it echoed down the hall.

I look around to see the damage:
The kid next to me fell flat on the floor,
Everyone else runs for the door.
How did my seat get wet? 1
