- For his father, see Dante Calabresi, Sr..
Dante Calabresi, Jr. was an Italian-American mobster and the son of Dante Calabresi, Sr..
When the Calabresi family thought that Fat Tony had gone soft, they attempted to kill him. After this incident, the Calabresis went to Fat Tony's compound for a sit-down with the Springfield Mafia. After clearing up the misunderstanding, Fat Tony and the Calabresis got along again with Dante Jr. hugging Louie. Michael D'Amico then came into the room with a plate of soufflés for everyone to eat. After Michael revealed that he made them himself, the Calabresi family laughed at him. Dante Jr. asked if he'd serve their soup cold if they killed Fat Tony, then asked if baby hot dogs were made like that or shrunk down. The Calabresis then attacked Fat Tony in a helicopter, hospitalizing him.
After the Simpsons became involved with the mob, Michael invited the Calabresis to the Simpsons house for dinner, to hand over all of Fat Tony's territory to them in exchange for the safety of his family and the Simpsons. He told Michael that the Simpsons should walk the dog once in a while to stay healthy. When the Calabresis started eating, they all died because the food was poisoned. As he was dying, Dante Jr. said he wanted to be buried next to his wife, under a bridge in New Jersey.
