Kopp's Custard Stand and Joe Biden

Vice President Biden was confused when he asked for ice cream instead of custard, but when that got straightened out he called the manager of the Kopp's custard shop outside of Milwaukee, Wis., a "smartass" after the man asked him to lower taxes.
Biden made the comment after the Kopp’s Frozen Custard shop manager told him that his dessert would be on the house if he lowered taxes.
"What do we owe you?" Biden is heard saying.
"Don’t worry, it’s on us," the manager replied. "Lower our taxes and we’ll call it [the custard] even."
"Why don’t you say something nice instead of being a smartass all the time?" Biden said a few minutes later.
