"Black comedy is a sub-genre of comedy and satire in which topics and events that are usually regarded as taboo are treated in a satirical or humorous manner while retaining their seriousness....
The purpose of black comedy is to make light of serious and often taboo subject matter, and some comedians use it as a tool for exploring important issues, thus provoking discomfort and serious thought, as well as amusement, in their audience."
A humorous skit and someone actually being assaulted are two different things.
