I'm a huge fan of the TV show LOST. It sucks that we have to wait until early 2010 to see the final season.
I happened to catch an old episode on the Sci-Fi channel a couple of weeks ago. It was the one where Dr. Arzt "blew up". It was so unexpected and hilarious!
Here's part of his bio from Lostpedia --
Dr. Leslie Arzt was a middle section survivor of Oceanic Flight 815. He was a science teacher who managed to discover many new species of insects and arachnids, including the Medusa spider, but was killed on the Island while handling dynamite on Day 44.
Arzt (played by Daniel Roebuck) only appeared in five episodes, but they were very memorable.
The first five seasons of LOST are available on Amazon.com --
