Two and a Half Men Season 1 Episode 3

Alan and Jake move into Charlie's beach-house permanently, ex Judith even helps arrange Jake's room. When the kid gets sick and insists on getting nursed 'at home' by his mother (who ruthlessly refuses any reconciliation move), Alan feels like a 'total failure', comparing himself to another guinea-pig which didn't survive Jake's neglect. Charlie takes Alan drinking and, when drunk, both of them conclude (with the help of the taxi driver) that the root of the brothers' problems is their mother, so she gets a nightly, yet ill-planned visit.
