I actually got called to the principle's office one year in high school. I was completely clueless as to why. So when the principle (think it was the assistant principle for my grade level, but...) finally saw me after a few minutes, I was quite curious.
"Why am I here?"
"Don't you know?"
"Nope."
"You've been written up on the bus. Once for having candy on the bus and twice for having a drink."
"That's why I'm here? Seriously?"
"Yes. What do you have to say for yourself?"
"Um, it was hot. I was thirsty. I had a few dollars on me, so I bought a drink."
"So, if you have money, you'll buy a drink?"
"If it's hot and I'm thirsty? Yeah."
"Just go."
Got back to class, and my teacher asked me how much time I had, to which I replied "none".
True story. Not sure that's word for word, but it's very close.
