Robert Griffin III Collects Socks
Collecting socks as a hobby is not entirely weird. Quite a few of them will even buy a house specifically for their collection for storage. Many collect shoes or clothes. For Robert Griffin III, his obsession is with socks. It probably started because of him being a military brat where clean socks are golden to any soldier. With parents in the military, people think they contacted a moving company to move their things for them, including furniture and socks.
People guess that the habit of collecting started from there. Robert III has such an extensive collection that, according to him, he can wear a pair a day and not have to repeat wearing one for two months. Also, when he accepted the Heisman trophy back in 2011, he was seen sporting a pair of Superman socks with actual capes — this made the audience adore him.
