a cool classic video game from the early 80s where you maneuver the joystick to place the little orangemonster Q-Bert on a pyramid of pads, changing their color. The goal is to land on all the pads on the pyramid to change all the colors. Then you commence to do the same thing at the next level (the next pyramid). Q-Bert must avoid bouncing critters (like snakes), if he's hit by one he cusses (a talk balloon filled with "swear word symbols" like "@#$*!" appears). If you're not careful with the joystick, Q-Bert could jump off the pyramid edge by accident.
I first played Q-Bert while I was at a bash with some friends at a Godfather's Pizzajoint. Their motto is "Pizza you can't refuse". Q-Bert is a thrill to play even today.
