A good actor makes their performance as realistic as possible - that's what draws the viewers into the performance. A few very talented actors in Turkey look like they should head out to Hollywood, because one viewer took their performance very seriously.
The aforementioned actors were performing in a goofy slapstick play, and one patron was so absorbed in the performance that she thought it was real. And she did not like the way the giant chicken and the incredibly obese man were treating each other. So she decided to do something about it. And her reaction (beating them with a stick) was so hilarious that the theater is considering adding her role into the play permanently.
