Oops!...I Did It Again - S2-E22
Continuity mistake: This episode establishes that Lily was born at the Live Aid event, which took place in July 1985. In the show's final episode, "Hello, Goodbye", Brad and Lily are graduating in 2005 (see the "congratulations" banner in a hallway at their school). Being born in 1985 would mean that she is graduating at age 20. It is highly unlikely that she failed and repeated two of her school years. Brad, who is the same age, is graduating with her, and he is a dedicated student.
Answer: "Take It to the Limit", while aired as the 13th episode, was the 7th episode produced for the 2nd season (production code 207). "Smoke on the Daughter" was the 8th episode (208) and "I Saw Daddy Hitting Santa Clause" was the 10th episode (210) produced. Often shows air episodes out of production order for various reasons. If they had aired 210 in order, it would have aired on Jan 23rd instead of Dec 19th, hardly a good time to air a Christmas themed episode.
