Glad it wasn't me

When I go into an museum or art gallery (yes, I occasionally go to them), I'm afraid that I would knock something over or damage something. So far nothing has happened. [Knock on wood]

Unforunately, it isn't the case for this guy. Poor guy knocked over two Ming vases when he tripped over his shoelaces. Now he is banned from the museum indefinitely. I guess I will making sure my shoelaces are always tied when I'm in a museum.
