So let's say you have only one Purdue serving tray. Your friends are over and you pile it high with potato chips but one friend needs low sodium. What do you do? WHAT DO YOU DO? Be prepared for that or almost any eventuality by having on hand TWO Purdue Boilermakers lightweight serving trays. And you can drill a hole through the center, add a mechanism and you have a dandy clock with a "P" at each hour position. So what time is it? It is ALWAYS Purdue time, you can tell your friends. That said don't worry about the time just enjoy the chips.
