Koichi is gives some of the best presentations. It is hard enough to be funny in one language, yet to be funny and understandable in two is quite an accomplishment. If you're ever at a Rubyconf, go to his talks. Also love the speed work he's been doing with generational GC. For a primer, Pat Shaughnessy has a great talk you should check out, also Ruby Under a Microscope is a good dive into Ruby.
