I guess I'm thinking about how much the cast from the BBT makes and how huge a hit it is and in syndication. Heck when I went to the UK last year and turned on the TV in my hotel room, what was on? The Big Bang Theory.
I'd never watched the BBT and didn't realize just what a huge show this was, but reading the full story and Chevy's comments that Galecki makes "$100 million a year" I googled him and figured it out.
I guess I'm behind the times.
