Meredith's facial condition is mentioned in a deleted scene. She says, "Some guys took me out on a fishing boat. I don't *think* I caught anything." She and Michael both refer to her face in another scene and she complains about how children have been calling her Hellboy. In the audio commentary, the writers explain that the original joke was that Meredith had a pool and a bunch of people were pretending to be her friend to get in on the pool. Finally Meredith got so sunburned that she didn't want to go swimming anymore. It was a running joke for the episode that got cut for time.

As Pam is running over to Jim at the gas station, she comments that "Montclair would have been closer" (as in, to meet halfway). Montclair is a real city in northern New Jersey, popular for its arts centers and restaurants.
