Plot hole: Garner is absolutely rubbish at playing basketball in this episode. The problem with this is that in an episode of Baywatch ("Lifeguards Can't Jump") - which happens in the same universe - his character is shown as being a very skilled basketball player.
Continuity mistake: When Donna jumps off the bridge, it's into relatively shallow water under the bridge, and there is land very nearby (at both ends of the bridge). When the camera shows her in the morning, she is suddenly far out to sea in the ocean. (00:01:51 - 00:09:33)
