Why is it...?

Have you ever noticed the strange, mysterious things that plague our world? Enigmas left unsolved, questions left unanswered.
Like, why is it that, if a novella is shorter than a novel, the word "novella" is longer than the word "novel"?
And why are those microscopic Halloween candy bars called the "fun size"? (In all reality, shouldn't the fun size be the size of a small car?)
Most importantly, who put the pocket in pita?Here are some more to ponder:
Why do we say something is out of whack? What's a whack?
If a pig loses its voice, is it disgruntled?
Do Lipton Tea employees take coffee breaks?
When someone asks you "a penny for your thoughts", and you put your two cents in, what happens to the other penny?
Why is the man who invests all your money called a "broker"?
Why isn't the word "palindrome" spelled the same backwards as forwards?
Why isn't the word "phonetic" spelled the way it sounds?
Why can't telemarketers pronounce my last name, even if it IS spelled the way it sounds?
Why do you go on my blog if all I'm going to do is ask you lame questions?
