Barry Bonds and his lies come to mind more than others. Why? Because he, unlike most of the other lying athletes, gets a 12-20 month stay in the federal pokey!
Of course, OJ will be the king forever. The dumb asshole literally gets away with murder (don't give me the "found innocent by a jury of his peers" bullshit, that fucker is guilty!) and then goes and gets himself at least 9 years in prison for robbery.
