Continuity mistake: In this episode Molly buys Mike a car but they end up returning it. However, in later episodes, they're seen driving it - it's even the "baby" Mike has to let go of (after going to the psychic).
Continuity mistake: After Mike's mother tells him that she heard a prowler, when it cuts to Mike and Carl showing up at her house we see that the window is wide open, but when they move in closer ordering the "sicko" to come out of the hedge, the window is closed as it should be, until Mike's mother opens it when she sees that the "pervert" is actually Kay.
