Firework sales are expected to hit a record $725 million this year, as cash-strapped states continue to loosen firework sales laws to raise revenue.

For the latter category, 76 Fireworks, one of the largest distributors in the country, sells something called the Jester's Revenge that retails for $250.

Personally, we'd go with the Shells—they seem more useful in a hypothetical revenge scenario.
