What are some of the interesting tidbits from the show? For example, the fact that Jeffrey Tambor played three roles on the series, then went on to play the Roper's neighbor. Or the fact that Lana's character was introduced that quickly dismissed. Remember Linda, Jack's off-and-on-again girlfriend? Why was her character so inconsistent? How about the fact that she "played" the role of Janet when Joyce DeWitt was absent during taping of the episode where Stanley thinks Chrissy is pregnant? I know these tidbits are well-known, but does anybody else have anymore?

That's Suzanne Somers in the first opening in a wig. That Apartment Building In the Beginning LOOKs NOTHING like the set. In the first six or seven seasons, the stairs were a dead end, but then suddenly they led to other apartments.
