11 seasons for Frasier is a remarkable accomplishment. Yes, a lot of the episodes were very similar, but even after 11 years the show is still high-quality television with some very witty lines from the entire cast. Roz was not in the episode, and I really do not think that many people were upset by this.
Felicity Huffman was great here as her sarcastic style of humor played perfectly off the tight-wound Frasier and Niles Crane.
"Dad, the chances of me knowing the score to the Mariners game are the same as you knowing the score to (some random play)." Lol, good one Frasier.
