This is weird...from current TELE sweepstakes.
“Any Canadian resident who is a potential winner of any prize must correctly answer a time-limited mathematical skill-testing question administered by telephone without assistance or mechanical or electronic aid in order to receive a prize. If a selected Canadian potential winner cannot be reached by telephone within a reasonable time period or answers the skill testing question incorrectly, as determined by Sponsor in its sole discretion, he/she may be disqualified, and, at Sponsor's discretion, the prize will be awarded to an alternate winner.”
