The lighthearted pranksters at Improv Everywhere held their Third Annual Black Tie Beach affair over the weekend. Participants wore formal clothes and went to the beach, despite the fact that a soaking wet ballgown seems like a bit of a drowning hazard.

Thankfully, nobody died. One couple did get engaged, though. And here we were thinking it's a good time when it's windy enough at the beach to fly a kite.
