When I find websites like this, my imagination rambles, and I found myself musing about how excited Dwight would get if he found out he could hook up a train horn to his car. And then of course he'd take it way too far and get into trouble, I wouldn't be surprised if Michael was involved as well.
Some of the best episodes featuring Dwight are the ones that expose his geeky obsessions, what with bears, farming, crossbows, karate, second life.
They're all hilarious.
