No Pants Day In New York City 2009

As an urban flanuer, one may observe spontaneous actions. "No pants day in the NYC Subway" is purely for fun, but it livens up the city in a whimsical manner. Should not cities be places of the unexpected, the unusual and the rediculous? The city can become the backdrop for open air spontaneous theater. Why can't theater be brought into places of work, play and commerce. There used to be a production company that would put on performances in the London Underground. I searched on the Internet, but found no reference fot this. It might be defunct. But, it was an excellent example of theater in a public place that contained an element of spontenaity.
