Recap / The Simpsons S 14 E 6 The Great Louse Detective
Someone's out to kill Homer, after Homer gets locked into a sauna by a hooded man — and only Sideshow Bob can figure out who that is.
Brick Joke: At the bar, Moe and the other patrons mock Bob's inability to kill Bart, with Lenny saying that if it was him, he'd just "slash (Bart's) throat all quiet-like." At the end of the episode, attempting one more time to kill Bart, Bob takes out a knife and says that he's about to take "some very good advice that was given to me, by Lenny."
Call Back: Most of Homer's past enemies were from previous episodes, including the son of deceased nuclear plant worker, Frank Grimes.
Human Cannonball: Bob gets into the cannon on one of the Mardi Gras floats and lights the fuse in order to launch himself into the air and save Homer from getting Impaled with Extreme Prejudice on one of the swordfish in the swordfish museum.
Jerkass: Homer's friends at the bar actually give Sideshow Bob advice and encouragement to kill Bart.
Sauna of Death: First attempt on Homer's life. He was actually already in danger by being in the sauna at all because of his obesity and heart problems. The sauna controls helpfully included the setting "murder".
