Shoddy Heat: Difference between revisions

| guests = * [[Topher Grace]] as Billy O'Donnell

To escape the heat, the Simpson family visits [[Grampa Simpson|Grampa]] at the retirement home to use his air conditioner. Grampa blocks Homer from feeling the cool air while [[Homer Simpson|Homer]] accuses him of never doing anything nice for him. The police come and ask Grampa for help. At the cemetery, where graves are being moved for new construction, they found a coffin containing two bodies and a business card for Grampa's [[detective]] agency. Grampa explains he was a [[Private investigator|private detective]] with Billy O'Donnell. [[Agnes Skinner]] asked them to investigate her boyfriend, [[Mr. Burns]], whom she suspected was being unfaithful. Grampa was busy caring for Homer, so Billy investigated and never returned. Grampa never looked for Billy. The police name him a person of interest.

Homer is not surprised that Grampa never looked for Billy while [[Lisa Simpson|Lisa]] wants to investigate. She tests the business card using a forensics kit and finds type AB-negative blood on it. She visits the DMV to find Billy's information, which confirms a matching blood type. She visits Grampa while the police watch outside. Records show Billy's car was abandoned where the powerNuclear plantPower Plant is now located. Grampa tells her not to investigate, but she is disappointed by his behavior. Grampa admits he investigated Billy's disappearance. He interviewed Agnes and began a romantic relationship. She confessed they followed Burns, and Agnes stayed in Billy's car while he went alone but never returned. Grampa visited Burns, but refuses to tell Lisa what happened because it would ruin Homer.

Grampa escapes from the police. Agnes shows Grampa dust that was near Billy's car. At Burns' mansion, Grampa reveals that, 40 years earlier, Burns said he sent Billy to paradise, but Grampa vowed to keep investigating. Seeing Homer behave foolishly, Burns stopped Grampa by offering to give Homer a job when he grows up and to never fire him. In the present, Homer overhears this and thanks Grampa, who deduces that the dust is from phonebooks used for constructing the power plant. He accuses Burns of killing Billy when he discovered this, but Burns phones Billy, proving he was sent to a tropical paradise to silence him. Billy told Agnes to tell Grampa, but Agnes, instead, wanted Grampa to kill Burns to inherit his fortune.

Later, Lisa asks the police who was in the coffin, and they said it was the business card printer who wanted to be buried with his wife as Chief Wiggum has salvaged some business cards from the grave.
