Short story about some guy in an audience that starts shouting at the devil and gesticulating at him and giving him "the fig" , which I guess is something like the finger or some other sort of gesture.
Many years ago, was part of a collection. I thought maybe Stephen King or Clive Barker but I searched their list of short stories and did not see it there. It is very funny and the guy is critical of the devil in a humorous way.
