Place a fountain glass on a dessert plate (to catch the overflow). Place a fountain glass on the plate and pour in the chocolate syrup, half-and-half or cream and cherry juice. Over-pack a scoop with ice cream and hang it on the side of the glass. Mix with a long spoon and fill glass with seltzer. Top ice cream with a loop-de-loop of whipped cream and a cherry. Serve with a straw and the long, mixing spoon. Yum-o!
