There was a movie with John Ritter, possibly 1980’s or 1990’s where he comes across a guy in the park dressed like a clown and pulled a gun on him. When he realized the guy was just an innocent guy who was dressed like a clown, he scolded him for “being dressed like that just begging to be shot”. I seem to remember that the John Ritter character had already had a run in with someone dressed like a clown. I think it may have been a serious comedy.
