In Supernatural's final season, a recurring joke found Sam and Dean Winchester using their law enforcement aliases as Agents Hamill and Ford -- a clear nod to Star Wars actors Mark Hamill and Harrison Ford.

Now, on Instagram, Hamill shared a short video that shows Dean reintroducing the old pseudonyms once again. In a caption with the video, Hamill joked that he was always up for a cameo with his old co-star, albeit only in spirit.

Dean creates fake photo identification cards whenever he and his brother needed to pose as law enforcement officers to gain privileged access while investigating the paranormal.

The final season had Dean bring back the fake identities to pose as officers with the U.S. Wildlife Service as he and Sam hunted a monster attacking campers. Sam was considerably more baby-faced in his old fake ID, while Dean hadn't visibly changed much since the last time they dusted off the pseudonyms.

Airing Thursdays at 8 p.m. ET/PT on The CW, the final season of Supernatural stars Jensen Ackles, Jared Padalecki, Misha Collins and Alexander Calvert. Following the mid-season finale, the show will return Jan. 16.
