Violet (Sadie Calvano) has plenty of problems in "Blow and a Free McMuffin." At first, a case of mononucleosis appears to be the main source of trouble for her — but as Christy and Bonnie (Anna Faris, Allison Janney) supply her with tender loving care, they soon find other factors are in play. Spencer Daniels returns as Luke. Mimi Kennedy also stars.
