The Sports Illustrated list of the 50 highest-earning athletes in the United States are golfers (you know Tiger Woods is No. 1 with $128 mill earned last year), basketball players, baseball players, NASCAR drivers, football players, and one boxer. It should come as no surprise that there isn't a single female on the list.

After Tiger Woods, the top ten is rounded out by golfer Phil Mickelson at No. 2 ($62.3 mill), LeBron James at No. 3 ($40.5 mill), Floyd Mayweather at No. 4 ($40.2 million), Kobe Bryant at No. 5 ($35.5 mill), Shaq at No. 6 ($35 mill), A-Rod at No. 7 ($35 mill), Kevin Garnett at No. 8 ($31 mill), Peyton Manning at No. 9 ($30.5 mill), and Derek Jeter at No. 10 ($30 mill).

Teachers, hide this list from kids who you're trying to convince to choose academics over sports.
