The Fetal Kick Catalyst - S10-E6
Factual error: When Raj, Howard and Bernadette are in the car, Raj puts on Batman the Animated Series to distract Howard from his back pain. Howard says "I'm in too much pain to watch cartoo-oh, this is a good one!" However, there is no way he could know that it's a good episode of the show because the opening theme song can be heard playing and the name of the episode does not appear until after it.
