A nice twist ending with the man dating Liz because he looks like her mother. This was a brilliant way to close the episode, and was almost as brilliant as not shopping at the store because "it's loud in there."
The Jack and Tracy storyline was interesting to say the least. In the early days of 30 Rock Jack Donaghy was extremely similar to Jack Gallo (played by George Segal on Just Shoot Me) and this was one of those episodes where they were extremely similar. That, thankfully, means that he was funny in the role, which he definitely was.
