Sic transit gloria mattress
(I just posted this as my Facebook status, but it's really more of a LiveJournal posting. Click the links for photos.)
Back in 1997, Sam and Arthur's Star Wars birthday party included an old patched waterbed mattress in the backyard as a block of carbonite, and a good time was had by all.
This summer, after Sam's waterbed mattress kept developing one pinhole leak after another for no reason I could determine, I got him one with thicker walls, and again put the old one out in the yard, where many people on my Facebook friends list among others have had fun jumping on it, lying around reading or napping or talking on it, etc.
Every day it would be covered with raccoon pawprints from the night before, until this morning when I looked out and saw that it was totally flat and covered with raccoon *bites*.
I think that there may be another old waterbed mattress in the garage, but that at this point putting it out should wait until next summer, when the raccoon(s) will have presumably moved on and/or forgotten that waterbed mattress = giant raccoon water fountain.
