Katey Sagal and Jack McBrayer will join the cast of The Big Bang Theory this season as Penny’s mother and brother, respectively, the show’s producers announced at San Diego Comic-Con on Friday. This will be the second time Sagal has played Kaley Cuoco’s mother on a sitcom; the pair previously co-starred on ABC’s 8 Simple Rules from 2002 to 2005. In fact, if you imagine that Amy Davidson grew up to look exactly like Jack McBrayer — a bit of a stretch, yes, but just go with it — why don’t we pretend this entire season of BBT is just an 8 Simple Rules reboot?
