In addition to LeBron's epic Pennywise performance, and Steph Curry's rendition of Billy The Puppet from the "Saw" films, we also saw Nashville Predators' defenceman P.K. Subban, Toronto Blue Jays third baseman Josh Donaldson, Danica Patrick and other athletes show off their best Halloween costumes on social media.
Floyd Mayweather also went all out this year, rocking four different costumes, tennis star Genie Bouchard channelled her inner Baywatch babe, and JR Smith pulled off a hilarious "Coneheads" costume.
Not to mention, last week Russell Westbrook and his teammate Nick Collison, along with their significant others, showed off their A1 "White Men Can't Jump" Halloween costumes, which deserve some extra shine today.
