This is quite funny. Cavaliers guard Kyrie Irving is quite boastful as he challenges Lakers guard Kobe Bryant to a one-on-one duel during training camp for the U.S. Olympic team in Las Vegas.

Irving wants to bet $50,000 to charity.

Bryant is funny, calling Irving a "high school kid," who played "two games in college." C'mon, Kobe, it was 11.

Irving actually thinks he can beat him. Don't sell him short.
