How many times have you seen the Big Bang Theory finale?
Only once. Is it common for people to watch it multiple times?
I don't know but I heard it ended quite emotionally so I thought it might have some replay value...
I'm sure I will watch it again. I just started it recently. It's been on for a long time, but I don't watch much tv.
Yea, they take up a lot of time.  Did you hear that a spinoff might happen?
No, I'm just surprised there aren't more. Young Sheldon is the only one I have seen.  
Is there a member of the cast you particularly like from that one?
I like them all really. Penny probably being the favorite. 
Did Penny and Leonard wind up having a child?
She was pregnant in the last episode. I assumed that was a sign of a spin off, but I have yet so see one.
