When Ed holds up the pen that Wendy gave him, when the writing of the pen is pointing up, he says "clothes on", then when the writing end is pointing down, "clothes off". But when Kyle picks it up, he has the writing end pointed down and says "Look, a lady in a bathing suit...", which by Ed's description she should be naked with it in that orientation.
Mike takes the cover off of the thermos twice when he tells Boyd to wash his hands.
When Ed walks in wearing his suit... he and Kyle reference it being what he wore to his third wedding, to his third wife. His third wife was actually his first wife who he married twice.
