“The Big Bang Theory” ended in 2019 before AI programs like ChatGPT and Midjourney really took off and developed a hold in the zeitgeist. It would’ve been interesting to have an episode centered on the characters’ thoughts surrounding the use of AI, but one thing included throughout the sitcom was “Dungeons & Dragons.” It was referenced in passing on many occasions and even factored into a few plotlines.

For example, Season 5’s “The Wiggly Finger Catalyst” sees the characters play some “D&D,” and Sheldon gets the idea to roll the game’s dice whenever he needs to make small choices, which results in him growing a mustache. The crew’s final “D&D” excursion was Season 12’s “The D&D Vortex,” where the main cast discovers Wil Wheaton hosts special, secret celebrity games of the tabletop RPG.

“The Big Bang Theory” touched on all things related to nerd culture, so it only makes sense for “Dungeons & Dragons” to factor into various episodes. But some cast members walk the walk in addition to talking the talk. Mayim Bialik and Kevin Sussman play “D&D” together outside of the show and engage in other nerdy hobbies. If “The Big Bang Theory” ever gets a revival, perhaps the game could come into the fold, maybe even with Raj finally taking on the role of Dungeon Master.
