25. Jose and Ozzie Canseco
Accomplishments: Jose: First-ever member of 40/40 club, 1988 AL MVP ; Ozzie: Atlantic League single season home run king (48)
Perhaps dubbing the Cansecos as "great" might be a bit of a stretch, but there's no doubting that these brothers provide more than their fair share of entertainment to the American people. Despite being the first baseball player in history to hit 40 home runs and steal 40 bases in the same season, Jose has managed to make people forget about his playing career thanks to his unabashed steroid use, his chronic case of Twitter logorrhea, and turn as a best-selling author. After failing as a baseball player (13 hits in 65 lifetime at-bats), Ozzie recently made headlines when he tried to swindle a club owner out of $10,000 by pretending to be his brother in a "celebrity" boxing match.
