I tease! It's show 200, and we've got Jon Skeet. Jon writes Java at Google, but he's also got a new book out called C# in Depth, Second Edition. Jon is also well-known for his answers on StackOverflow, gaining him the title "The Chuck Norris of Programmers." Listeners can get 40% off with code "HanselC40" at http://manning.com/skeet2 until March 15th.
