The idiot who says "Good luck, everyone." on the National Lottery doesn't mean it, and hasn't even thought it through properly.
How can everyone be lucky any how? Just supposing they were, the consequences would be disastrous anyway- they'd either all end up winning a proportion of the jackpot smaller than their initial stake money, or bankrupting Camelot by winning larger numbers of the smaller fixed amount prizes than had been budgeted for.
Doesn't add up.
Furthermore, I have reason to suspect that Lottery HQ is in fact not a real building but a crude computer generated facsimile and doesn't even have real helicopters with searchlights flying over it (unlike our neck of the woods on a Saturday night).
I do hope the BBC reconsiders and puts an end to this wicked deception of the credulous...
