This is great. In a series of ads for American Express, Seinfeld hangs out around town with Superman. The cartoon Superman. They're less like ads than short skits, and they're hilarious. Also be sure and check out the
interview with Seinfeld and Superman on the Today show. My favorite from the skit (they're sitting in a diner chatting):
SM: I thought we were going bicycling today, Jerry?
JS: Um, nah, it's not real fun bicycling with you.
SM: (confused) Why not?
JS: (looks at him for a moment) It's just not.
