Aargh!

The piano keys were sticking. Bad. I was pretty sure the kids were to blame, so I started poking around inside the piano. Look at all the "treasures" I found:

(I also found a 25-year-old love letter, which I have chosen not to include here so as not to incriminate anyone, lol.)

P.S. I'm pretty sure I also saw a dead scorpion and a dead spider in there, but they gave me the heebie jeebies so I didn't get close enough to thoroughly investigate.
