Dan Harmon's celebrity-studded roleplaying sessions. Complete with faux 80's style animations.
Besides being great entertainment (episode 4 made me laugh so hard my wife turned up her TV and scowled), it has some great tips for gaming. Although not everyone may like how the games are run or played, here is what I'd steal:
Plot the adventure between points on a map
Allow one shot guests to shine
Value gear over gold
Only roll dice when absolutely necessary
Let players try anything
Keep your tongue in your cheek
Contribute to either the game, the atmosphere, or both
Stay in character so long as it adds to the entertainment
Try anything but don't break the game
Roll with the punches
Anyway, off to Canada tomorrow! Hip hip hooray!
