Alfonso Ribeiro of The Fresh Prince of Bel-Air might do the nerdiest, preppiest dance of all time.

But that didn't stop hundreds if not thousands of followers from joining him yesterday at Universal CityWalk and other locales in an attempt to break the record for the largest flash mob in North America.

They performed the awkward “Carlton Dance:”

Musical inspiration included “It's Not Unusual” and “Apache.”

Did they break the record? It doesn't seem clear, but Ribeiro claims victory, saying that people in 300 cities participated:

[Update at 1:45 p.m.]: We got a press release from “ViSalus™ – home of the Body by Vi™ 90-Day Challenge,” which sponsored the event, stating that “unofficially counted numbers (to date)” comprised about 10,000 dancers. At Universal CityWalk the crowd count was 320, according to the statement.

Did they break the record? Doesn't seem likely. The statement still calls the events an “attempt.”

The company said the following cities also had “Carlton dance” flash mobs:
