Acting Debut
Jason Ritter technically made his debut on the show without even knowing it. Jason said to the Huffington Post, “The story is they were shooting a bunch of things at the zoo and I got away from my mom. I just walked into the shot and it made Joyce DeWitt laugh so they kept it in the opening credits.” The opening credits from seasons six through eight kept Jason’s “incident” as it was comedic gold.

The apartment that was home to the three main cast members got three different addresses throughout the show.
