It seems that there is legal precedent under California law for this suit to exist (the story would likely be much different if it was a private party or, perhaps, a free show), but this also looks like a very twisted, flawed understanding of how to bring about equality between the sexes by the men suing Shlesinger. 

Men just can’t have enough, can they? 

Whatever happens will be an important distinction for live entertainment, especially, in regards to comedy shows going forward.

You, however, can take a tiny sliver of solace in the fact that the plaintiff’s name is George St. George.
