Four Score and Seven Migraines Ago - S1-E86
Continuity mistake: After reminding Lincoln of his address on Pennsylvania Avenue, Wakko, Yakko and Dot simultaneously change positions between shots, moving closer to a table on the train cabin floor.

Continuity mistake: When Yakko points to India, Africa, except for Egypt and Madagascar, is shown as almost one country with no borders, until he points to Tunisia.
Yakko: How's it going, Scratchy?
Dr. Scratchensniff: I take umbrage at that.
Yakko: Oh, sure! Take all the umbrage. Don't leave any for us.
Question: Why do the Warners fear Baloney?
Answer: According to the Animaniacs Wikia: "Baloney is one of the few people capable of truly terrifying Yakko, Wakko and Dot, largely due to being impervious to their violently physical brand of humour and his inability to understand how much they despise him."
