Maggie announces that she's been married for 22 years and 4 months. This is inconsistent with the season four episode "Anniversary from Hell," where it sounds as though Jason & Maggie's wedding was in 1969, but falls in line more with the 1968 date mentioned in season two's "The Awful Truth."
While watching Ben's movie, there is a part where Ben is in a plane and his plane tilts far over sideways. The Seavers tilt their heads to follow Ben's movement in the movie. However, not everyone is tilting their head in the same direction to follow Ben.

In this episode, Jason and Maggie are celebrating their 20th anniversary a few weeks late. This episode aired in early 1989, meaning they got married sometime in 1969. However in Season 2's "The Awful Truth," 1968 was quoted as being the year Jason & Maggie wed.
