A The earliest written record of the phrase being used is Robert Burton's Anatomy of Melancholy of 1621, in the form "Set a beggar on horseback, and he will ride a gallop".
Widely regarded as an old Irish proverb, the exact origin of the hell-bound version is unknown although the saying means that if you give someone an unfair advantage, they will misuse it.
Later versions were shortened to " set a beggar on horseback" to signify someone who is corrupted by new- found wealth.

The Mario franchise, which began with an appearance in the 1982 arcade game Donkey Kong, has sold more than 201 million copies.
Halo 3 creators Bungie took great pride in declaring Halo 3's launch as the "biggest in entertainment history"
