Thanks to my wonderful Celebrant colleague from New York, Valerie Coleman, for forwarding this video. It's a surprise wedding reception, staged by Improv Everywhere. It made me day!
In a follow-up from the ImprovEverywhere blog, here is from an email sent by the couple after their surprise reception:
"Whatever becomes of our “scene” we just wanted to say thanks because it was freakin’ hilarious. The most important thing for us is that you gave us just about the best wedding story anyone could have to pass on. Take good care."
