Funny Jokes

A fifth grader looks sad, so her teacher asks, "What's the problem? I hope it's not homework again."
"Well, uh, yes it is," the little girl says. "I accidentally made my homework paper into a paper airplane."
"That wasn't a very bright thing to do," says the teacher, "but just this once, I'll let you just unfold the paper and hand it in."
"Oh, but that won't work," the girl says, looking even sadder. "You see, the plane was eaten by my dog."
