In The Big Bang Theory episode 'The Dependence Transcendence', the guys struggle to finish their government project on time before Air Force Colonel Williams (Dean Norris) returns. Meanwhile, Penny (Kaley Cuoco) and Amy (Mayim Bialik) go to what they think is a party at geologist Bert’s house. Last time we saw Bert was in the 2014 episode ‘The Occupation Recalibration’ when he gave Amy some unwanted attention.
Bert is portrayed by Brian Posehn. He’s known for his roles on New Girl (Biology Teacher), Guys with Kids (Victor), The Sarah Silverman Program (Brian Spukowski), Reno 911! (Stevie the Coroner), and Just Shoot Me! (Kevin Liotta), among others. The Big Bang Theory airs Mondays at 8pm on CBS.
