Little Johnny looked so sad his teacher had to inquire what was wrong. “What’s the problem?” she asked. “I hope it’s not about your homework again.”

“Well, uh, yes it is,” Little Johnny says. “I accidentally made my homework paper into a paper airplane.”

“That wasn’t the smartest thing to do,” said the teacher, “But, just this once, I’ll let you just unfold the paper and hand it in.”

“Sorry, but that won’t work,” Little Johnny replied, looking even sadder. “You see, the plane was hijacked!”
