In the episode in which Mike and Gloria are fighting, right after the babysitter cancels, a large shadow moves very noticeably up and down behind them on the bookshelves and walls.
The quote that Mike reads during the wedding is the same quote that Reverend Chong reads at the double wedding in "The Stivics Go West." Gloria says it's the quote that Mike read at their original wedding.
Mr. Tannen: You ride a motorcycle, Reverend?
Rev. Harris: Well, you know what they say: 'The Lord moves in mysterious ways.'
Michael: Hi, Jack!
Jack: (trying to be funny) Never say that to an airline pilot.
