Last Laugh is the twentieth episode of season three of CSI: Crime Scene Investigation
A comedian is poisoned on stage and his death turns out to be connected to the death of a teenager. Meanwhile, a woman in her bathtub drowns and the CSIs don't think it was an accident.
Grissom and Catherine investigate the murder of an insult comic named Dougie Max (Jeffrey Ross) who dropped dead on stage after drinking from a tainted bottle of designer water. Warrick is sent to a convenience store to investigate the death of a 15-year-old boy only to find out the boy died after drinking the same brand of water. The cops trace the water and other acts of hostility to a comic who hated Max's lowest-common-denominator comedy and attitude, and who has an on-stage breakdown where he confesses to killing Max and laments that an innocent kid got killed as well.
Brass asks Nick and Sara to investigate a case he ruled an accidental death after spotting the 'grieving' husband in a very expensive new car. They figure out that the husband's story of an accidental drowning isn't backed by physical evidence, and deduce that the wife was drowned by the husband while taking a bath. The case can't be prosecuted, but Brass talks to the husband's insurance company and gets them to impound the car, with promises of more civil liabilities and a continuing criminal investigation to come.
