Make them memorable.

Of course, if you chose the wrong career, say, accountancy, rather than firework manufacture and display, you may be at a slight disadvantage with some of these.

A nice story from the Register - well, rather a depressing one really - about Camelot, the UK's lottery operator, having to withdraw a recent scratchcard competition:

According to the Manchester Evening News, to qualify for a prize, punters had to "scratch away a window to reveal a temperature lower than the figure displayed on each card". Sadly, as the card had a decidedly wintery theme, this initially-shown figure was often below zero. ... Among these was Levenshulme's Tina Farrel, a 23-year-old who admitted "she had left school without a maths GCSE". She explained: "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." ... "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."
