Home Oil Change and a bunch of other random questions

Quick question, may be a matter of opinion, but thought I'd see what people say:

When draining the oil, if the truck has been sitting for a couple days, is it better to run the engine up to temp first or just drain it while everything has obeyed the law of gravity and made it's way into the pan? I know hot oil flows out better, but it seems silly to pump all that oil up into the engine just to heat it up and wait for it to drain back down.

Personally, I don't see much difference in the end. Thoughts?
