The first time I heard about a flash mob was on “Jamie Oliver’s Food Revolution.” Jamie was trying to drum up interest for his cause on a college campus, and he used a dancing flash mob to get everyone’s attention.

Watch as a flash mob entertains at Marin Farmers Market in California. This should brighten up your Monday.

A flash mob, according to Urban Dictionary, is “a group of people who appear from out of nowhere, to perfom predetermined actions, designed to amuse and confuse surrounding people. The group performs these actions for a short amount of time before quickly dispersing. Flash mobs are often organised through email and/or newsgroup postings.”

If being part of a flash mob sounds fun, you can check out People post dates and times for flash mob activity. In fact, according to the site, a group is trying to organize a laughing flash mob at the Bellingham, Wash., farmers market on Sept. 18. They hope to get the market laughing for thirty seconds straight.
