The Big Bang Theory’s Season 10 premiere was a guest star-studded affair, with lots of people showing up for Leonard (Johnny Galecki) and Penny’s (Kaley Cuoco) wedding.
The most notable part, though, was that it was a mother/daughter reunion for Katey Sagal and Kaley Cuoco.
That show was Cuoco’s first big job before The Big Bang Theory made her a household name, so it was sweet to see them onscreen together again.
