Are you watching "The Comeback" -- the HBO comedy series that stars Lisa Kudrow? I just discovered it on HBO On Demand yesterday and proceeded to watch all four available episodes. It's excellent. Kudrow's a terrific comic actress -- you really sympathize with her as she's being humiliated, even when most of her problems are in her head or a result of her own doing. When she names her puppy "Lucy," you don't need her to say she loves Lucille Ball. You could already see that.
Anyway, she plays an actress from a once-popular sitcom who's being relegated to a secondary, older-woman role on a new sitcom and who's simultaneously making a reality show about her comeback. We see a lot of the "raw footage" for the reality show and the behind-the-scenes work on the sitcom, so there is a lot of mockery of two types of TV shows.
Note: I've only watched one episode of "Friends."
