I think 3 is nonsense. Time doesn't proceed a day at a time, it proceeds unceasingly, so people are deliberately being more specific by stating what unit they're currently basing their lives on. Mr Buress seems to be under the misapprehension that nobody knows this and he has to point it out.
Sorry if my analysis spoils the joke, but it was past spoiling anyway.
I thought 2 was the best, but he won last year.
