First YouTube, then Facebook, now Mexico — Yahoo just can't cut a deal with anyone. Mexico has retracted its approval of Yahoo's new promotional stunt, beaming a laser version of a time capsule filled with items submitted from around the world from the Pyramid of the Sun in Teotihuacan.

In February 2002, with things at rock bottom, a former dot-commer brought a truck full of tumbleweeds to South Park and let them roll across the lawn.

Dan, if you're reading this — can we get a little backstory? Were they filming the opening credits for "The Big Lebowski 2: San Francisco"?

Dan gets reactions from South Park workers, but they only deepen the mystery:

"It was a punch in the gut," Margaret Mason said. "It was a representation of everything everyone had been feeling."

"It was a perfect metaphor," said [Max] Applegarth.

"It was dumb," said people in general.
