I'm Cool With It, But...

How did cottage cheese become a staple of salad bars everywhere?  Don't get me wrong; I love cottage cheese, and I'm glad it's always there.  But... it's not salad, nor is it something I've ever seen anyone put ON a salad.

Itsy Bitsy Peanut?

Why do we use the phrase in a nutshell when we're summarizing something?  I mean, I get that nutshells aren't that big, but my explanations, no matter how brief, would probably not fit in a nutshell.  Unless it was a coconut.  Except that's not a nut, is it?  Now I'm confused and hungry.

Yum?

Why does everything that's so tasty have to be so incredibly bad for me?  Why can't chocolate just be a vegetable, dammit?
