This legendary Mariners fan keeps dancing like no one's watching

Seattle Mariners fan Robert Ruvkin has been entertaining the crowd with his truly awful dance moves for decades, and on Monday night's game against the Rangers, cameras caught Ruvkin racing through different sections of Safeco Field to show off his unique style. 

Ruvkin used to work at the Kingdome in the 90s, and in 2013 he was honored with the Mariners Fan Lifetime Achievement Award. According to MyNorthwest.com, Ruvkin goes to a handful of games each year. He once starred in a classic Mariners commercial featuring Lou Pinella and Alex Rodriguez.
