beards are a stupid rule too. But we aren't hypocritical there at BYU. It's flat out no beards. Caffeine its only against the sodas. It's ok to eat Easter candy, chocolate at the Wilk, hot chocolate at LES etc. In my opinion, all of that should be avoided anyway. The Mormon culture is very contradictory in the caffeine nature. It's very weird.
Shorts are a rule only at BYUI.
