Write numbers on X number of pickles slices (X = number of owners in league), and assign a number to each team. Then, a la Billy Madison, throw them against a pane of glass. First to the bottom gets first pick, and so on.
Seriously, names out of a hat. That's the only way I've ever done it.
Is there anything fluffier than a cloud?
If there is, I don't want to know about it.
