If those sound stupid, it's because "at the end of the day" is equally stupid. They all mean the same thing.
Maybe if you use it in a literal context. I'll take the garbage out at the end of the day. At the end of the day I'll count the register. That's different from Stephen A. Smith saying "At the end of the day, Tony Romo just didn't score enough touchdowns to win the game." I almost want to start caring about sports again just so I can trash the ESPN mongoloids who make basic comments like this.
I've heard it used as a metaphor for "in summary" many times. It's like really basic people that say "it is what it is" and "workin hard or hardly workin!" and talk about weather a lot. Just horrible.
I had to google it just to make sure I'm not being too cynical. I'm glad I did:
At the end of the day
A saying mostly used by people trying to prove points without having any other intelligent way of expressing it.
Person 1: How do you feel about the continuing threat of nuclear proliferation
Person 2: Well at the end of the day...nuclear weapons must be stop.
at the end of the day
Rubbish phrase used by many annoying people.
at the end of the day i got the last laugh because i shagged his wife
at the end of the day
An irritating verbal crutch, indicating closure or synopsis, for morons who are incapable of finishing a sentence without incorporating at least one tired cliche.
And so, at the end of the day, when all was said and done, we wrapped things up and we were all happy campers.
