HBO's Watchmen isn't known for featuring any post-credit scenes, but that's about to change."Friendly heads-up to Watchmen viewers: Don't switch off this week's episode when the closing credits start," tweeted pop-culture writer Keith Phipps. The episode, entitled "A God Walks Into a Bar," is the season's penultimate episode and airs on Sunday, Dec. 8.

The series has not featured any such scenes to date, and the contents of the pending scene aren't yet known. The episode title is a possible play on words relating to Angela Abar, aka Sister Knight, who was revealed to have had a past relationship with Doctor Manhattan in last week's episode.

Post-credits scenes have become anticipated and almost expected in superhero films, and in television series to a lesser extent. Watchmen has taken a different approach, one more in keeping with the original comic. Instead of additional scenes, backmatter material is shared via HBO's "Peteypedia" page, and features fictional interoffice memos and news clippings related to the show's events. The name of the page is derived from FBI Agent Dale Petey, a member of the government's anti-vigilante task force on the show.

Developed by Damon Lindelof, HBO's Watchmen stars Jeremy Irons, Regina King, Don Johnson, Tim Blake Nelson, Louis Gossett Jr., Yahya Abdul-Mateen II, Tom Mison, James Wolk, Adelaide Clemens, Andrew Howard, Frances Fisher, Jacob Ming-Trent, Sara Vickers, Dylan Schombing, Lily Rose Smith and Adelynn Spoon. The series airs Sundays at 9 p.m. ET/PT.
