The "Harlem Shake" has taken the world by storm in a unique way -- unlike other YouTube sensations, where people watch and play the video millions of times, the dance apparently inspires others to make their own creations.
According to NPR, the University of Georgia men's swim and dive team performed the dance underwater, and the Norwegian army did it in the snow.
But when some Egyptians decided to join in on the fun, they were apparently arrested.
According to the Agence France-Presse:
Egyptian police said Saturday they have arrested four students who filmed themselves publicly dancing in their underwear, as more people around the world emulate a viral dance craze called the "Harlem Shake."
The four pharmaceutical students shocked residents of a middle class Cairo neighbourhood when they removed most of their clothes and videotaped themselves performing the pelvis-thrusting dance, a police official said.
The hostile audience tried to assault the students, who are accused of committing "a scandalous act," the official added.
Egypt has strict public indecency laws. [Emphasis added]
Egyptian media has reported on the incident, but few are posting the exact video.
It seems the Harlem Shake is actually quite popular in Egypt -- a YouTube search shows at least 3 videos filmed in the post-revolution "Arab Spring" nation.
The first seems to be the most likely contender -- (content warning: the video does show 4 men dancing in their underwear):
This one is also gaining a lot of traction, though. Filmed in front of the pyramids, the group says they were eventually stopped by police, but managed to record a 30-second video (same content warning):
