About TWO AND A HALF MEN

Another year of bachelorhood brought many new adventures for roommates Walden Schmidt and Alan Harper. After his girlfriend turned down his marriage proposal, Walden was thrown back into the dating world in a serious way. He got invited to a threesome with Alan and his girlfriend, Lindsey, and then created a false identity in order to find a girl who wasn't after his money. When Walden's old friend Missy came to visit, Jake fell so head-over-heels for her he went AWOL from the Army. The guys may have thought things were going to slow down once Jake got transferred to Japan, but they were proven wrong when Jenny, a niece of Alan's who shares more than a few characteristics with her father, showed up at the beach house.
