Dice Cup (For games like Yahtzee)

Is it just me or do you find those dice cups that come with games like Yahtzee annoying. How hard would it have been to mold those cups with a flat bottom so THEY STAND UP when passing the cup from one player to another. Well, you're prayers have been answered. This cup not only stand up, but has an ergonomic shape that fits both large and small hands.
