Koohii stories:

1) [matticus] 3-11-2006(265): Don't give water to a skeleton. When he drinks it, it'll sluice right through his bones, forcing you to put one of those "Caution - Slippery Floor" signs up on the resultant puddle.

2) [Ramchip] 10-6-2008(98): Slippery surfaces are very dangerous for skeletons, since their bone feet slip easily… a few drops of water, and zweep! A large mess of bones to pick up and reassemble!

3) [jameserb] 19-5-2008(23): Caution: Skeletons in these waters indicate someone didn't abide by the "slippery when wet" sign.

4) [dtcamero] 17-6-2010(15): WET SKELETONS are notoriously SLIPPERY.

5) [Captain+Kanjipants] 27-2-2010(13): Most slippery when wet signs show a picture of water to caution you. This one goes a little far by showing a skeleton laying in the middle of a pool of water.
