I am a sports fan. However, I think it's fair to say that NFL football is the small screen equivalent of fast food:
1) You consume way too many empty calories; you consume way too many empty minutes.
2) The menu options are limited; the entertainment options are limited (thanks, Joe Buck, for that enlightening segment highlighting how an ump's job is to clean and dry the football with that, and only that, special towel.).
3) When you're all done eating, you feel an unshakable shame at having consumed so much junk food; you need a week to recover. When you're all done watching, you feel an unshakable shame at having wasted so much time listening to Joe Buck, et al.; you need at least a week to recover.
I don't even know where to start with Overtime.
