Charlie Harper and Alan Harper, "Two and a Half Men"

Upon divorcing his wife, Alan Harper (Jon Cryer) and his young son moved into his brother Charlie's (Charlie Sheen) home in Malibu. Charlie was a devout bachelor and an alcoholic who earned his living writing jingles and ... moresongs, hardly an appropriate role model for Charlie's son Jake. The new season of "Two and a Half Men" will introduce us to a new roommate for Alan and Jake upon Charlie's death.
