John Frost at TheDisneyBlog got to visit a completely impromptu practice run of the Laugh Floor last week. This is the show which replaces the Timekeeper, and is themed after the comedy routine done by the one-eyeball Monster. At least I think it is. I didn't read John's musings, since I prefer to be fully surprised by what I see, the first time I see it. But many folks like this kind of spoiler, so I thought I'd link to it: http://www.thedisneyblog.com/
The show isn't in normal preview mode - he got a one-time deal there, I think.
