Outsource EVERYTHING

This post is a little facetious, but only a little.  The more I look at outsourcing opportunities, the more I believe it's the right answer for so many things.  Whenever you can find somebody who specializes in a task that you need done, why would you want to do it yourself?  OK, I know that's not always right.  Pricing certainly is a factor, but what else?  What are things that should NOT be outsourced?
