The Grand Poobah
One of the more fun parts of having an old friend be your boss, and of having another old friend work in your group is that sometimes, you can be a little silly. Hence Heather and I have renamed our fearless leader Mr. Brady (since we now have 6 people on our team, which is divided into 2 distinct groups of 3 just like the Brady kids. Although, who's Tiger then, and what about Alice?) or the Grand Poobah, depending.
Every time I see an email addressed to Mr. Brady I can't help but snicker, out loud, to myself. Then pretend like I was coughing.
