The pool room at the bar shown in season 4 "Archie is Cursed" is no longer there.
Archie reminisces about hearing long stories from Edith's father, but on season three's "Lionel Steps Out" it's stated that the man died before Edith had met Archie.
According to Archie, his first words to Michael were "Are you Jewish?"
In fact, in the episode Flashback: Mike Meets Archie, Archie's first words to Michael are "Look Edith, he wore his Halloween costume." (Note: Those words were actually spoken to Edith. Archie's true first words to Mike were "Put it there", after being coerced into shaking hands with him, and there was no mention of asking Mike if he were Jewish).
After Archie and Mike get locked in the storeroom, Mike attempts to ram the locked door open by running into it with his shoulder. This is a rather stupid thing to do, as illustrated when the two of them walked into the room and the door opened into the room and not out into the hallway.
