After Lisa’s saxophone is destroyed, the Simpsons reminisce about how she originally got the instrument. On the hottest day of the year, Homer must decide whether to buy an air conditioner or replace Lisa’s sax.

Lisa's friendship with Fat Tony's son Michael prompts mob boss Tony to invite the Simpsons over for dinner. Michael says he'd rather be a chef than take over the family business, but that's before Tony is shot by a rival mobster.
