This display of mathematical brilliance comes to us from the land of Nigel Tufnel.  Apparently, to win in the Cool Cash scratch-off lottery, you have to reveal a temperature lower than the target.

"On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn't.

"I phoned Camelot and they fobbed me off with some story that -6 is higher - not lower - than -8 but I'm not having it."

I liked the comment in this discussion thread:

I prefer the Zen lottery ticket, where you have to not scratch anything, to match the empty box below.
