Mona tells her friends and family that she doesn't want to celebrate her birthday, as she would rather spend the day alone in quiet reflection. However, she soon becomes extremely bored. She is relieved when Big Dee Dee shows up, although she has actually forgotten Mona's birthday and is just there to see Dee Dee. The two go down to the laundry room in pursuit of Big Dee Dee's dog, and wind up trapped when an earthquake hits. They share a picnic lunch and have a revealing talk about their relationship. Meanwhile, Phyllis tracks down Charles to try to convince him to help buy a car for Mona's birthday, and they wind up stuck in an elevator. The earthquake also traps Dee Dee, Adam and Spencer in an upscale store as they shop for Mona's gift. Everyone is embarrassed when Spencer has a panic attack after the earthquake.
