Playing himself, the "Star Wars" actor showed off his comic chops while officiating the wedding of Sheldon (Jim Parsons) and Amy (Mayim Bialik).
But he also may have changed the pet-naming galaxy forever. Howard (Simon Helberg) finds a lost dog and calls the owner. Hamill himself shows up at Howard's door to reclaim his pooch, gobsmacking Howard, who learns that the dog's name is Bark, as in Bark Hamill. (Yeah, we loved that, too.)
Howard strikes a deal with Hamill to hitch Sheldon and Amy instead of giving him a reward ― and keep it a secret from the pair. Of course, Hamill commands the big day. He fields questions from wedding guests during a delay ...
And gives all Luke Skywalker fans some moments to love and cherish.
Twitter ate it up.
And some were clearly smitten with Bark Hamill as well.
