Parents need to know
Age 10+Language, sex talk, violence in live-action sitcom.
Parents need to know that The Big Bang Theory S2 E20, "The Hofstadter Isotope", is a live-action sitcom episode. The series is known for more innuendo than the science jokes suggest, but rarely explicit. Sits in the gray area mainly on swearing (moderate, in dialogue). Violence is mild but includes Howard says, "Get it? I mean, they’re laughing, we’re laughing, and then we get them up to about a .15…". Sexual content includes Howard says, "I’m a horny engineer, Leonard. I never joke about math or sex"; Howard says, "Okay! Let me just go inside and slip off my underwear". Language isn't constant, but you can expect swearing — for example, Raj says, "Well, what are we waiting for? Let’s bounce, bitches". Characters drink or talk about alcohol and drugs — Howard says, "Which means, as the evening progresses, we will get better looking courtesy of 99 cent…". Every flagged moment below is a direct quote from the transcript or a short description of what happens on screen.
