Apparently "flash mob" dances are still a 'thing', because the cast and crew of "The Big Bang Theory" recently did one to Carly Rae Jepsen's "Call Me Maybe".

It was all organized by Kaley Cuoco, who plays Penny. She got her sister to choreograph it, and about 40 or 50 people surprised the producers by busting it out during a live taping a few weeks ago.

CBS posted the video on YouTube yesterday.

The music starts at :13, and the cast joins in at :33

I feel like this is as good a time as any to mention that I am a HUGE fan of 'The Big Bang Theory'! If you're not watching it, you're missing out on some of the funniest and wittiest material on television. Guest stars like Stephen Hawking, Stan Lee and Wil Wheaton make it even better for nerds like myself.

I should also point out that I didn't even know about the show until they started airing re-runs on TBS (very funny). Since I discovered it, my DVR has been maxed out with episodes.
