(OT comment fodder: What's the main difference between Superman and every other good-guy super hero?)

On TV you only get 30 or 60 seconds. On the web you get as much time as you can get people to give you - they call then “webisodes.”

American Express teamed up Jerry Seinfeld and Superman. If you have a few minutes, it's pretty amusing and fun. Seinfeld's not Batman, or The Flash, and he's not going to team up with The Man of Steel to save the world. But they might sell some credit cards, and I laughed.

NOTE: American Express has removed the content from their servers, but you can still see the webisodes over at Unplugged Studios, the creators of the Jerry and Superman films. It's a little tricky now because their site is Flash-based, so here are my convoluted navigation directions:

• Go to http://www.unpluggedstudio.com/
• Enter their flash site
• Look at the bottom for the American Express link.
• Click on that link and use the menu on the right to choose the "Watch" options. From there you can watch all four episodes.
