Get the UMSL mug.
IKEA-designed stepstool used in the Anheuser-Busch Hall College of Business administration to allow students to reach the drinking fountains where Budweiser flows like water.
That petite TriDelt always has to use the UMSL when she wants to get a buzz on after her Business Stat class.
