Little Johnny looked so sad that his teacher had to ask what was wrong.
Teacher:
“What’s the problem? I hope it isn’t about your homework again.”
Johnny:
“Well, uh, yes, it is. I accidentally turned my homework paper into a paper airplane.”
Teacher:
“That wasn’t the smartest thing to do. But just this once, I’ll let you unfold it and hand it in.”
Johnny looked even sadder.
Johnny:
“Sorry, but that won’t work.”
Teacher:
“Why not?”
Johnny:
“You see, the plane was hijacked!”
