I ate breakfast this afternoon at 1 PM at a Taco Bell. This kind of eating is not uncommon among comedians; it's probably why the average comic rarely lives past his mid 30s.
After I ordered, the person waiting on me asked "regular" or "supreme". I asked what the difference was, she said: "Supreme is the same taco except with sour cream."
I'm sure you already knew this, but I want you to think about it: according to the people who run Taco Bell, the only difference between an ordinary something and a supreme something is sour cream.
Here's what Webster's has to say about the word supreme:
1. highest in rank, power, authority, etc.; dominant
2. highest in quality, achievement, performance, etc.; most excellent
3. highest in degree; utmost
4. final; ultimate"
Or... sour cream.
I realize that it's just some stupid sour cream, but I think this might be a big reason why our country has been slipping a bit in recent decades; the devaluation of our superlatives. For instance, "awesome" used to be a word that was once reserved for acts of god; now it's routinely used to describe pizza.
Advertising plays a large part in this. When you're trying to sell, you can't be reasonable. You can't say: "Mop and Glo: it'll make your floors temporarily less dirty." You have to say "Mop and Glo: It's so unbelievably awesome and astounding, it will literally knock the shit right out of your colon" or some such.
Eventually, all the good words get co-opted for silly things. You do this enough and the good words don't mean anything anymore. How can you give someone a compliment that has any kind of real resonance?
"Dr. Jonas Salk will forever be remembered for his supreme accomplishment: curing Polio."
It's not unreasonable for the average kid to think that all Salk did was take Polio and pour some sour cream on it.
