I assume everyone knows about this sweepstakes. So I started reading the offical rules, to look up some dates or something, and I saw this odd rule. #7 WINNERS, near the bottom, it says " Each Canadian resident who is a potential winner will be required to answer correctly a mathematical skill testing question without assistance of any kind whether mechanical or otherwise to be declared a winner and be eligible to collect a prize." Look it up. Am I reading it wrong or what. Is it a joke?
