Little People

What is with Hollywood's pre-occupation with "little people?" They comprise approximately .0001 percent of the population, but they are forever in movies and on TV shows.

I just don't get it. Not that there is anything wrong with it - Mickey on Seinfeld played off Kramer beautifully. The scene where they are wrestling who to sit next to at dinner is priceless.

But they just seem oddly ubiquitous in Hollywood, given the odds of encountering one in real life. All I'm saying.
