It also has a number of fight scenes, which are dangerous, and is often darkly lit. I don't know if you could really control for all of the variables, but the thing about the name is just a fun joke among theater people. Few actually believe it.

I will note that the worst injury in my troupe's 20+ year history was during a production: a one in a million bounce by a blunted stage weapon. It is the only time anyone got taken to the hospital. But there have been other injuries, and the last time I directed that play I made sure the injury count was zero.

(Credit to my fight choreographer, who made sure of it.)
