How long have they been like that?

Now you all should know I am putting in a lot of time an effort from my busy holiday schedule to search the web for the best videos, clips, pictures whatever.

My newest find...Grand Central Station. This is not really funny as just so cool. It is on the same basis as the group dancing video in Liverpool Street Station but different. At first I thought well this is okay, but as time goes on more and more people get freaked out by what is going on. Now I would love to do something like this! Who is down for this in Old Town Square?

PS. the group is called Improv Everywhere and they have a lot of other cool videos on youtube. Check 'em out.
