In the Family Guy episode titled Take a Letter, Lois Griffin takes a job as a postal worker. This decision is made to cover the costs of Stewie's private school education. While working, Lois discovers a letter that Peter Griffin had written but never sent. The letter was addressed to Gretchen, who was an old fling of Peter's. The letter is dated one week before Peter and Lois were married. Following the discovery, Gretchen attempts to come between Lois and Peter. However, Lois develops a plan of her own to address the situation.
