Chet is the best suitcase. His belly button and nose hair will blow you away, literally. If you are lucky to run into a Chet don't forget to give him a cake, he will in return give you an all access pass to bridge.
Dylan: "Did you feel the lovely breeze coming from Chet's bellybutton today?"
A Chet is not just a person but also a state of being. If you meet Chet remember to get them a snow globe for if not might risk angering it and doom yourself to eternal suffering.
