Around the early 80's there was a movie mainly revolving around kids doing pranks. One scene was two boys calling a person telling them not to answer the phone because the phone company was working on the lines, then they called the person back threw an apple in the disposal turned it on and then screamed when the person answered. There was also a scene where the boy was supposed to be dressed as a wolf for halloween but they kept saying he looked like a pig because his mask was big and round. They went to an old lady's house and were sneaking around and she was shooting at them with a shotgun. Despite my description, it was really funny.
