The Big Bang Theory has steadily featured a number of geek icons over the years, with familiar faces like Summer Glau, Katee Sackhoff and George Takei appearing at one point or another. Now in it's 12th and final season, the series is bringing a stacked cast of guest stars together for an upcoming episode.

The Twitter page for the series released a brief teaser, revealing that the upcoming Duengons & Dragons-themed episode of the sitcom will include cameo appearances from across nerd culture, all locked in an "epic" round of the classic role-playing game. Kareem Abdul-Jabbar, Joe Manganiello, William Shatner, Kevin Smith and Will Wheaton will all be featured in the episode to some degree.

It's likely we'll get to at least a few of them actually playing D&D in the episode, especially Manganiello. The actor is an avid fan of the tabletop game and even donated a number of game editions to charity earlier this month. There is no confirmed air date for the episode.

Starring Johnny Galecki, Jim Parsons, Kaley Cuoco, Simon Helberg, Kunal Nayyar, Mayim Bialik and Melissa Rauch, The Big Bang Theory airs on Thursday nights on CBS.
