One of my favorite memories when playing games growing up is finding out the secret code to turn on the blood and uncensored fatalities on the Sega Genesis Getting it from a friend at school and rushing home to try it out (ABACABB). If this was done correctly, the text will turn yellow and you will hear Scorpion say "Get over here!" 

A nod to the Abacab album by the band Genesis who shared their name with the console.
