So because a guy makes a joke like that in an interview of odds of "300-1", that makes it a fact?
Seriously? 
Like I said, it's a fact because I remember it quite well, a friend of mine (huge soccer fan) even bet 100 dollars on it.
It's not uncommon for different bookmakers to have different odds, but you might want to learn the basics of betting and what "arbitrage" means before posting such utter nonsense. I take it you didn't do too well at math in school.
Resorting to personal attacks now? Usually when people stoop that low they're out of arguments. Then again, in this case you never had an argument to begin with.
I just have to LOL now because math was always one of favorite subjects in school, I have worked as a software developer, business analyst, data analyst, professional poker player and have made some decent coin with sports betting on the side and now you're insulting my math skills, thanks for the laugh. The funny part is that my math skills are irrelevant here, I could be a professional basket weaver who can't add 2 and 2 together and that has nothing to do with the fact that a friend of mine made a bet 30 years ago where the odds were so remarkable that I remember it to this day.
I might as well say Canada were 10,000 to 1 to qualify for that tournament. Now I don't have any proof of that, just like you don't have any proof of your "fact". But I'm pretty sure of that line, so you can guffaw all you like but yes, it is a fact.
Expecting me to prove what odds some bookmaker in Toronto was offering in 1986 is not very smart. Do you understand why? Give it up already, you're making yourself look foolish. The bookie I knew offered 200-1, the article I linked to mentioned 300-1, it's a fact, I know it, if you don't believe it good for you, I really couldn't care less
