It's a quote from The Marvelous Mrs.Masel
A-See that guy over there in the gray suit? Marty Segal. Yesterday, he scored his first Copa gig. Big, big deal.
B-He just spilled coffee on his suit. Does the Copa know about that?
A-That may be his opening bit.
I have 2 questions:
What is a COPA? I checked the dic it says something like football games but still confused me.
What's the meaning of opening bit?
