Just ask these stand-up comedians, who have been doing sets on trains for months. There are tickets, but then there are also random subway riders. And is it official? Hm. “The show had the chaotic air of something that could get shut down at any moment by a strict police officer who was not in the mood for a joke. A few people sipped beers, but everyone wore face coverings, making reactions to jokes harder to decipher. Still, the comics said they could tell from crinkled eyes and body language.” – The New York Times
