Improv Everywhere

"Causing scenes of Chaos and Joy in public places" is the site's mildly anarchic theme. It's creative, it's fun and it shows what happens when people take an interest in what's going  in their surroundings in everyday life, which is better than having your head buried in an iPod all day. On the other hand, the actors in these scenes sometimes fib (or outright lie) to keep the skit moving. Still, depending on your kid's age, it might be important to have a conversation about the importance of time and place when making jokes.

Not many, but a few, videos contain images of people dressed in just underwear from the waist down -- some of which is "barely there" underwear -- in subways. Some of the posted comments include frank discussions about homosexuality and religion.

A few Google ads. Ads for the ImprovEverwhere book. Links to T shirts and other participants' sites who are in the videos. Lots of brand-name places associated with where the improv videos are made, such as McDonald's, Starbucks, Abercrombie & Fitch, but not directly promotional.
