Back in the 80s, ruthless street dealers dealt Big Head Codes, a nefarious set of commands which, when carried out in a videogame, caused characters to have huge heads and little tiny bodies.

The forbidden fruit of these codes proved so intoxicating that a government probe was launched to determine whether the practice was illegal or merely stupid.

A few game developers decided they’d had enough of the practice and formed an agreement to incorporate the codes themselves into games and make these codes available to the general public. Games including NBA Jam began to make Big Head Codes a standard feature in the series.

Big Head Code dealers found themselves out of business and moved on to dealing crack and heroin. Everyone lived happily ever after.
