My dd18 first showed me this video a while back. It was my introduction to Improv Everywhere, a group dedicated to spontaneous public performances and pranks. Check out their site for more of their hijinks.
This clever concept now has its imitators, not surprisingly. Here’s a very nicely done public performance in Belgium (you’ll especially enjoy this if you’re a fan of “The Sound of Music”):
Oh, I love these things!
If they all result in such GOOD feelings as I enjoyed while watching the Belgium one (couldn’t see the first for some reason), I think it’s WONDERFUL!
Janet, they are fun, aren’t they?
Tori, don’t know why that first one won’t work for you—sorry! And I love the Belgian one too
