12 Bar Blues
performed by NRBQ

While at a steakhouse, a trucker named Red challenges Homer to an eating contest, ending with Homer losing the match and the trucker losing his life from "beef poisoning". To make it up to him, Homer becomes a trucker and takes Bart along for the ride. While asleep, Homer discovers the Navitron Autodrive system. After conversing with other truckers, Homer decides not to release information about the scam. When passers-by find out though, a mob of truckers confront Homer. To get home, Bart and Homer are coerced to take a freight train with napalm. Meanwhile, after deducing that only Homer and Bart get to do the fun things in life, Marge and Lisa decide to excite their lives by installing a new doorbell. However, after no-one presses the doorbell, Lisa presses it herself, causing it to malfunction.
