Yes, I went as Pat for Halloween. I have no idea what made me think of it, but that's what I did. It was actually really easy to pull off (which is kind of scary). I bought a wig and glasses, darkened my eyebrows with black eyeliner and wore no other makeup. I wore a pair of my own khakis and found an old denim shirt of Bret's, along with a black belt and some black oxfords I bought for Halloween a few years ago (we went as The Blues Brothers), and there you go.
Everyone at the party knew who I was right away and cracked up. So, it had the desired effect. I guess I am more into getting the laugh than taking the opportunity to dress uber-slutty like the trend seems to be right now for Halloween (there was a middle-aged woman dressed as a Playboy bunny and another as a pirate-wench with serious cleavage at this party).
Anyway, I had a good time and it was worth it, even if there are now pictures of me with my shirt tucked into my pants. Eesh.
