There is a great interview with Patrick Fischler over on the Blog. He sounds like a neat guy. Apparently he loved playing Jimmy Barrett, even getting socked by Don Draper. Every actor that talks about their role on Mad Men seems to really appreciate that they were part of something special, as indeed they were. I hope Jimmy Barrett shows up occasionally in future episodes, if only to irritate Don. It adds more spice and depth to the show when characters like his show up once in awhile and don't just disappear like they never happened. A Jimmy B. and Joan Holloway affair could be very interesting - he surely noticed the lovely redhead when he visited the Sterling Cooper offices, right? Anything to get Joan away from the rat doctor.
