Good One! (Spoilers)
6 April 2009 | by See all my reviews

In The Great Louse Detective the first time that they permanently used computer animation rather than hand drawn is a good way to start. Sideshow Bob episode have never failed me yet. The main plot of the episode is that the Simpsons go to the Spa but while they are at the Spa someone tries to kill Homer by locking him in a incredibly hot steam room. Chief Wiggum decides to release Sideshow believing the best way to catch is a criminal is by using one. Homer learns that he is to become the king of Springfield Mardi Gras. At the parade Bob learns that Homer's engine is having a problem because of the repair of the mechanic. He draws a correlation between the wrench that was used to lock Homer in the steam room. Bob and Homer chase the killer when they learn it is Homer's Mechanic Junior. He admits that his name is Frank Grimes Jr. The police arrive and Frank Grimes is arrested. Later that night Homer puts Bart to bed but the minute he closes the door Bob is hanging to the back of the door. He is about to kill Bart when he finds he cannot because he has grown accustomed to his face. Bart watches as he leaves out of the window and Bob is electrocuted by two birds who play the remote on there nest. I just love how Bart wont stop shocking him in one part. I thought the whole Frank Grimes Jr. thing was pretty obvious for the most part. Overall good.
