It is spreading like fire and almost every school has had its students forming groups doing the "Harlem Shake" and posting it across the Web.

However, some students are finding that their 30-or-so seconds of online fame is coming at a fairly high cost.

About a100 students across the US have been suspended for making and posting their own version of the viral video on the Web.

School districts have offered a variety of reasons for the suspensions. The videos feature suggestive and inappropriate dancing.

The decision has been compared to the plot of the 1984 film "Footloose," in which a town outlaws dancing and rock music.

The viral shake found its way to lavatories and the aisles of airplanes as well as corporate offices.

Defense Science Board recommends U.S. take critical steps to improve "cyber" defense, as well as offense.
