Brooklyn Nets team owner Mikhail Prokhorov is, uhh, eccentric.
The obscenely wealthy oligarch invited Stephen Colbert to spend a day with him at his mansion in Russia. They toured Prokhorov's luxurious home, held massive guns, played with ninja stars, threw axes in a colorful dungeon, and Prokhorov even showed Colbert his profoundly strange exercise routine that he once made the Nets do in training camp.
So yeah, very eccentric.
