A dance called the "Harlem Shake" is going around online right now.  In the past few weeks, a ton of people have uploaded videos of themselves doing it, and they're all set to a song called "Harlem Shake" by a DJ called Baauer.

--The dance basically involves humping the air and waving your arms around in pretty much any way you want to.  So in other words, it looks like a bunch of people who CAN'T dance.

--There's one video where two old women do it . . . the website Smosh.com posted a list of the "Best Harlem Shake Videos So Far" . . . and even the staff of Anderson Cooper's talk show got in on the action the other day.

Yesterday we hadn't even heard of The Harlem Shake, and today we're almost getting sick of it..
