Shh! You are in a library!

Reader's Digest 11月号の記事 'Laughter The Best Medicine' からの引用です。
A blithering idiot enters a building and goes to the counter. "I would like a large soda, a humburger, and french fries, please," he says.
The woman behind the counter says, "Sir, you are in a library!"
The B.I. looks around and notices others sitting quietly and reading. He leans in to the librarian and whispers, "I would like a large soda, a humburger, and french fries, please."
