Taxi - Season 3 - Eps 14: Louie's Mother
Louie is reveling in the news that he's moved his mother out of his apartment and into a nursing home and is throwing a party to celebrate, inviting only Alex. Alex grudgingly shows and learns that the party is a sad affair, the only other guests being three losers that soon leave to go to another party. Louie confesses to Alex that he's actually depressed-- his mom actually moved out after they had a fight and he misses her. Louie's depression gets worse over the days to come and Alex convinces him to go make up with his mother. Louie goes to see his elderly mother, who initially won't speak to him, but eventually agrees to come home with him and all is well again.
