I was browsing through Beta Search tonight and came across Bill Murray. For TV programs it listed Saturday Night Live. I looked at upcoming episodes for Saturday Night Live and there don't appear to be any that actually include Bill Murray. Looking at the cast for Saturday Night Live they appear to include everyone who was ever a cast member.
If this is the way it's supposed to work then it's going to be kind of frustrating. If I'm looking up Bill Murray I really don't care to see SNL listed if he's not actually in any of the episodes.
