Leaving aside his personal life of beating Hooters waitresses, getting his ass kicked in Mixed Martial Arts and getting busted trying to smuggle fertility drugs from Mexico, Canseco is the kind of guy who lets you spend the whole day with him for $3,000, because a day with a washed-up MLBer is totally worth as much as a used car.
Ironically, this is the same car Canseco drives.
In short, the guy had everything and pissed it all away, except for the ego; that he seems to have kept.
How He Was Right:
In February 2005, because he needed to pay rent, Canseco put out a book called Juiced in which he divulged that all those home runs and amazing feats he accomplished were made possible by a generous grant from the Steroid Corporation.
Yes, Canseco wrote an entire book about how he was cheating the entire time he was wowing crowds, and he tried to play it off as a great thing because Jose Canseco approves of steroids, and Jose Canseco is always right.
