HALES CORNERS, Wis. (CBS 58) -- A few Bucks players spent their day off giving back to fans. People of all ages lined up for hours on Thursday for their chance to meet the Greek Freak.

"He's tall and he's humble," said one fan.

Giannis signed thousands of autographs at the Pick 'n Save in Hales Corners.

Fans couldn't contain their excitement and Giannis says that the feeling was mutual.

"You know it's just fun, just to interact with the fans because a lot of them cannot go to the games so it's fun to come out here and meet with them and sign autographs and just hang out with them," Giannis said.

The Bucks said a few thousand fans showed up to the event.
