We had to take a three-hour nap yesterday afternoon, so that we could stay up past our bedtime and watch Mötley Crüe preform on "The Late Show With David Letterman." We had been promised pornstars on network TV, and we were sure that something wonderfully exciting and dirty would happened to make it all worthwhile. Boy, were we wrong! Yes, the girls were there, and there was even a fourth as-yet-unidentified babe on display ... but "displayed" was all they were. The girls just sat motionless in the shadows for four minutes. No dancing, no makeouts, and they weren't even introduced. What's worse--The Crüe didn't even play "Dr. Feelgood"! And now you know why we're going to be tired and grumpy all day today.
