To cut a long story short is just a very common expression that people use when they are trying to tell you the basic details of a story. Adam said, "I shafty the riggles in my pockles" Riggles just means wrigglies. Rigglies is a very, very famous brand of chewing gum. So he didn't say wriggles. He said wriggle. And pockles is just his word for pockets.
