According to his transcript, George P. Burdell has been a student at Georgia Tech since 1927. How? He was invented out of thin air when student Ed Smith received two enrollment forms. With Smith’s help, “Burdell” attended all his friend’s classes and took all the same exams.

For a nonexistent person, Burdell turned out to be pretty ambitious. Smith graduated in 1930, but his invisible friend stuck around, adopted by other students. He eventually earned a master’s degree and became an official alumnus, then flew 12 bombing missions over Europe in World War II. In 1969 he signed up for a whopping 3,000 credit hours at Georgia Tech — and began a 12-year term on MAD magazine’s board of directors. In 2001 he was briefly the leading contender among voters for TIME magazine’s person of the year.

Strangely, after 79 years of school Burdell is still only a sophomore. He’s majoring in civil engineering, according to a recent report card.
