The 30-year-old Olympian attended a men's basketball game at Arizona State University, Thursday night stepping out wearing only his gold medals, a bright yellow Speedo and matching swim cap and a bow tie that shocked everyone including the college basketball players.

Reports dished out that the revealing get up done by Phelps was all part of ASU's student-run "Curtain of Distraction," a legendary tradition led by the “942 Crew” in which fans in the student section aim to fluster a free-throw shooter from the opposing team by revealing some kind of distraction behind a black curtain.

Apparently such stunt clearly worked out, a player from Oregon State, Stephen Thompson Jr., missed two foul shots!

According to Entertainment Tonight, Phelps has been using the university's facilities to train for the 2016 Olympic Games -- which he says will most likely be his last -- in Rio de Janeiro, Brazil. After his Olympic retirement, he reportedly plans to be an assistant coach for the Division 1 ASU swim team, currently led by his longtime coach, Bob Bowman.
