Men Behaving Badly is the story of best mates Gary (Martin Clunes) and Tony (Neil Morrissey), two thoroughly modern lads - politically incorrect, unreconstructed, with a penchant for finding as many excuses to sit on the sofa and drink as much lager as they can. Kicking them into shape is Gary's no-nonsense girlfriend Dorothy (Caroline Quentin) and Deborah (Leslie Ash), the woman upstairs.
