S18E01 The Mook, the Chef, the Wife and Her Homer
The laughing kid of the school kids' car pool, Michael, is all of a sudden feared by everyone when it comes out that he is the son of local mob boss (or, as he says, "garbage businessman") Fat Tony. Everyone but Lisa. She tries to get to know him and finds out all he really wants to do is becoming a chef, cooking being his greatest passion. When Fat Tony is severely hurt by a whacking attempt, carried out by a rival mob considering him vulnerable for his son won't take revenge in case of his death, Michael doesn't feel like he can take over the family business. So Homer and Bart, feeling responsible for the new friends of the family, offer to take over while Fat Tony is recovering.
