I was in my school's bathroom and one of the teachers heard me snickering to myself. (She was using the bathroom, I was just washing my hands)
Later, she gets me in class and takes me back to the bathrooms and says, "I believe you're responsible for this."
And she opens the stall door, lifts up the toilet seat...AND THERE'S THIS HUGE TURD!
And she tells me to flush it! But I told her I didn't do it. So she flushed it.
I'm so serious! I'm not even making it up. I swear.
