UNIVERSITY PARK, Pa. — In 1906, upperclassmen at the then-Pennsylvania State College voted to have freshmen wear something to distinguish them from the rest of the students — thus the tradition of the "dink" was born.

Easily identified by the small beanie caps, freshmen were expected to know Penn State trivia and history and were often randomly called upon by upperclassmen to prove they were knowledgeable about their new school.

Freshmen were required to wear their dinks in class, traveling around campus, and at sporting events, and to tip their caps to passing upperclassmen. If discovered inappropriately without a dink, a freshman could face a student tribunal and be quizzed about Penn State, or be required to sing the Alma Mater in public.

Male freshmen wore blue-and-white dinks — except from 1932 to 1937, when dinks were green (to denote the "green" students' lack of understanding of how to behave in college). Female freshmen wore green ribbons in their hair until 1954, when they also adopted the dink. The practice of "freshman customs," including the wearing of dinks, was, for the most part, discarded in the late sixties.
