Usually if you do something whether good or bad, it comes back to visit you later down the road. Sometimes it comes back quickly and it's called instant karma. This story I read came from shooting a movie, The Wolf of Wall Street. So DiCaprio in his films goes for realism. In one scene he's supposed to hit Jonah Hill in the face. So, Jonah Hill really gets hit in the face. Hill doesn't like that one bit. Hill knows he can't pay him back the same way. He has to use his brain. He becomes an active participant in his eventual payback or karma.
In one scene, DiCaprio is eating some sushi (yellow fin tuna), he turns to Hill and asks do you want to eat the rest? In the script Hill is suppose to say yes and eat it. But Hill changes it to No you eat it to DiCaprio. During the rest of the takes Dicaprio has to keep eating the fish for the next 2 hrs. At the end of the takes, DiCaprio is tossing his cookies in a circular file. Everyone is asking Leo are you going to be ok? While Jonah and Scorsese the director are on the floor laughing hysterically.
Way to go Jonah!
