As a result, he tells his father, Nick Katsopolis, that he wants to leave the pest exterminator business that is run by Nick, and he is severely disappointed by this. So disappointed, that Nick loses his temper with Jesse and "kicks him out of the family". Jesse and his mother Irene manage to talk some sense into Nick, who realizes that Jesse has a dream about making it in the music business, and the 2 work things out. Meanwhile, Stephanie is afraid to go to the dentist to get a tooth filled, and she's even more nervous when she's actually sitting on the chair that's in the examination room.
