My cat often does the most hilarious things... but I don't usually have a camera handy.
The other day, she was taking her ease on the bathroom vanity, as per usual, but she was facing away from the basin... which we always keep filled with fresh water for her, since she likes to hang out there. She was flicking that tail around like mad, unconcerned at first that it was getting wet... until she flicked it upward and got splattered in the face. She jumped up like her ass was on fire: "WHAT WAS THAT??? WHO DID THAT???" I thought my son was going to have a hernia from laughing.
