Re Creation Puns

So My roomate invited me to his family Thanksgiving/holiday party yesterday. After dessert we're all sitting around and the children present are being rowdy. My roomate's brother calls them all over to our table and insists on showing them how to make a duck call. He begins ripping apart an empty soda can and wrapping it up in a very complicated fashion with a napkin and a plastic fork. He meticulously takes the top off, makes strips of metal, and winds them into this plastic fork. He carries on like this for about five minutes, the children utterly transfixed, sit watching until his creation is finally "complete". He then holds it up to his mouth, inhales, and shouts: "HERE DUCKY DUCKY DUCKY!!!"
