Goodnight Sweetheart/Funny

"Gary: You know, I read somewhere Stephen Hawking is close to unraveling the mysteries of the universe. Good, maybe he can give me an answer for why Time Travel gives me gas?"
 * Gary's evil twin in "Mine's a Double" singing "Anarchy in the UK" at the Royal Oak.
 * When he travels back to Victorian London, Gary is mistaken for Jack the Ripper, and is chased by an angry mob. He manages to duck into an alleyway, and the mob goes in the other direction. He breathes a sigh of relief...then the camera pans out to reveal that Jack's standing right next to him.
 * Gary's lament in one episode.
