Whatever Happened To Bert Kibbler After The Big Bang Theory?

Brian Posehn turned his "nerd" interests into a career. For one thing, he got to make guest appearances as three different members of the Pakled race in an episode of the animated sitcom, "Star Trek: Lower Decks," called "The Spy Humongous." Over in the rival franchise, he also made an appearance in the pilot episode of the Disney+ "Star Wars" series, "The Mandalorian." He even got to dip his toe into the Marvel universe, playing General Dagger in an episode of the "MODOK" animated series called "Tales from the Great Bar Mitzvah War." Beyond that, he can be found on his weekly podcast, "Nerd Poker," about the fantasy role-playing game, Dungeons and Dragons, which he started in 2016.

From 2020-2021, Posehn starred in the TruTV series, "Top Secret Videos." In a format that seems to harken back to "Mystery Science Theater 3000," "Top Secret Videos" features three comedians — Posehn, Ron Funches, and Ali Kolbert — playing NSA interns in a razor-thin plot that's mostly just a set-up to allow the comedians to make jokes about popular viral videos.

Posehn is still actively doing voice-over work. In addition to his "Star Trek: Lower Decks" and "MODOK" appearances, he also had a recurring role on "Steven Universe" where he played Sour Cream, the zen and soft-spoken DJ. Overall, nerdiness seems to have paid off for Brian Posehn in a big way.
