Mike Tyson has once again outraged the boxing world with his tasteless predictions for his fight against Francois Botha. Here is a selection of the x-rated thoughts on life he has uttered over the years.

"You know what I do when I'm right - I put people in body bags" - warming up for the Francois Botha fight.

"I want to split his nose and drive the bone into his brain" - before his fight with Tyrrell Biggs.

"I want to kill him. That's what I want to do, kill him. Absolutely. There is no point in elaborating" - before his fight with Razor Ruddock.

"I don't see him laughing at the end" - correctly predicting the result of his second fight against Frank Bruno.

"Evander Holyfield is lucky I didn't bite his throat" - after the ear-biting shame that cost Tyson a £2 million fine and his licence.

"Why do I have to relive my f------ life" - outburst to his own lawyer during the New Jersey hearing to win back his licence after the Holyfield ban.

"I have no self-esteem but the biggest ego in the world" - evidence given to the New Jersey State Boxing Board last year.

"Prison was a nightmare. I saw rape and robbery. They tried to break me but they couldn't" - on the three years he served in jail for rape.

"When they wrote about the old- time champions who had girls lining the dressing-room walls they called them heroes. When they say the same about me I'm supposed to be a perverted, sex-craved psychopath" - the year before he was charged with raping a beauty pageant contestant.

"I truly think everybody hates me. I truly believe that because no one gets punished more than I am" - last year on ABC television.

"You can't really trust anyone. Everyone - the white man, the black man, the red man, the yellow man. I accept they are all out to get me" - in a 1995 TV interview.

"No one gives a f--- about Mike Tyson. If someone accuses me of a horrible crime they say yeah, he's capable of it" - feeling sorry for himself last year.
