And Bud seems to try to avoid putting the ice cream in his mouth as though he had some aversion to it- really strange- Lou puts his spoon into it (making the cherry roll on to the table) and it doesn't look like it's shaving cream or anything but ice cream. Why is Abbott unwilling to put even that minuscule amount into his mouth? Maybe it doesn't go well with bourbon?
