I HATED that module. I was overseas when it came out, but I special-ordered it based on the title. When it arrived, I started reading and couldn't believe it. They'd turned Castle Greyhawk, the premier dungeon of the setting, into a joke. Now, I have nothing against humorous dungeons, but to have a whole thing be a joke was too much. I suppose I was expecting something else, so the disappointment was intense. In any case, between Castle Greyhawk and modules like "Puppets," "Childs Play," and "Gargoyle" it seemed to me that TSR was sending a pretty un-subtle message, which was "Greyhawk is a joke."
Maybe I'm reading too much into that, I don't know. I do know that I quit buying TSR's Greyhawk material.
I'm all for OSRIC so I can use OSRIC-compatible materials in my C&C game.

Actually, I doubt many people will
play "OSRIC" -- AD&D faithful will probably continue to play "AD&D" using OSRIC-compatible supplements. I suppose someone could play "OSRIC" if he didn't have the AD&D rulebooks, though.
