Two and a Half Men Season 3 Episode 7

Charlie wakes up drunk with stalker Rose in his bed, presuming they 'did it' a second time in two years. Alan is all but helpful when Charlie, whose fears Rose's revenge is shared by Bertha, gets a surprise visitor: Rose's super-rich dad Harvey. So Charlie is relieved when normally unwelcome mother Evelyn hits it off romantically with Harvey and takes him away. A few days later, she turns to her boys for help against the 'live-in' stalker, and gets it from another relative.
