By carefully observing my friend Tony and his sartorial habits I was able to pull this off.
I had noticed we had the same shirt, and I caught on to the fact that this shirt seemed to make it to the top of his choices on Mondays or Tuesdays. And so with great strategy this last Monday, I finally managed to come into work dressed as Tony. These are great times on the Internal Medicine service at Kijabe Hospital. (I think I need a life!)
