The plot of the episode is Bob became a model prisoner and is recommended for early release. His brother Cecil offers him a job to supervise the construction of the new Springfield dam. However, Bart does not true Bob's intentions and tries to investigation.
A lot of the humour is based on Frasier, and this episode combines the best of the Simpsons and Frasier. Grammar and Pierce pretty much play the same characters on that show in this show. As well as the sibling bickering, there are moments of comedy genius ranging from great lines like 'You'll live to regret this', and psychical gags like when Bart and Bob are falling down the dam. Frasier is obviously referenced a lot in this episode. The episode also ways as a good thriller. This episode is a great example of the Simpsons at their best. This is the last good Sideshow Bob episode. Italian Bob was okay, but still not as good the previous Sideshow Bob episodes.
This episode is easily a classic.
