Ach!!! As usual, it's far worse than originally expected. Not only did the Martians shut down the Mudcat, they actually managed to totally infiltrate the server and mate with the Mudcat Catfish! Here, see for yourself! It also appears that as a side effect of their infiltration they absorbed huge amounts of knowledge from the million-plus posts that are stored on the server's hard-drive. They are now qualified to teach anything from Finnish folklore to quantum physics. They also now know twelve different ways to finger a D7 chord, but it doesn't do them much good as they now have fins instead of fingers.
