From Tiger Woods to Tony Hawk: Athletes take on Halloween

The culmination of spooky season is upon us. On Monday, teams, athletes, mascots and at least one celebrity fan got into the Halloween spirit.

Connor McDavid channeled Tony Montana. A'ja Wilson ran the "Scooby Doo!" gamut. Tony Hawk went full Larry David. Singer Ciara and her daughter with husband Russell Wilson, Sienna Princess Wilson, did their best impression of the Williams sisters.
