15. The Butterfly Effect Effect

Complete story — includes the ending

The episode starts with Alex, Dave, and Penny playing indoor baseball in Dave's apartment. Soon after, they end the game and discuss how they wish it were spring. They talk about how the beginning of spring is heralded by Brad and Jane's annual "Spring Smackdown", an annual fight between Brad and Jane that signals spring is coming and that Max can come out of hibernation (throughout the episode Max acts increasingly like a bear, including attacking hanging meat, growling, eating out of a garbage can, and riding a unicycle). Brad and Jane arrive and seem like they will start the fight, but do not.
