Married... with Children: Season 7, Episode 3

7 - 3: Every Bundy Has a Birthday

When Peggy discovers that no one knows Seven's birthday, she picks one at random, Al's. He is understandably not pleased when he has lost his birthday to the new kid. Peggy decides to have a small party for Seven's 6th birthday at a local park. But the party fizzles when a snobbish rich parent arrives and declares the park private for his own son's party.
