Decent episode with a fun guest star,but not as good as the first few episodes of the 23rd season,
8 December 2011 | by (Ireland) – See all my reviews

Replaceable You is a good Simpsons episode,although maybe not as fun and enjoyable as the previous three episodes of the 23rd season,although I did enjoy the side story as well as the guest appearance of Jane Lynch as Roz.

Homer gets a new co-worker named Roz (Jane Lynch) who,at the start seems nice but it turns out shes trying to steal Homers job,meanwhile,after Bart and Martin win a science fair with a robot baby seal,they decide to make more and make a fortune of it,especially for the Springfield Retirement Home.
