10 bonus points for anyone who knows what movie this quote is from. Our doorbell was broken and I had to put a sign on it because people kept thinking they were ringing it. Then I thought "That would be so funny to put 'bell out of order...please knock.'" I was waiting for someone to ring it anyway (it did sort of work sometimes) so that I could stick my head out and say "Can't you read" and they'd say "Read what?" and I'd say "The notice" and they'd say "What notice?" etc.

Jerel didn't think it was funny at all, but my friend's 4 and 5 year old daughters knew exactly what it was from. I'm so cool.
