Through a Lens Darkly - S1-E20
Continuity mistake: When Tom lifts up the girl's sweater (with both hands), he is still wearing his shirt. In the very next shot, he has magically lost his shirt too, even though his hands aren't free to take it off, and the girl wouldn't have had time to do so in the space of 1 second.

Continuity mistake: At the end of the episode, Tom is absolutely drenched because the car has crashed into a river, and he has to wade through the river to get to the riverbank. However, as he walks away, he doesn't leave a single wet or muddy footprint behind him despite this.
