All color monitors and television sets have a built in degauss circuit that fires when it's powered on from cold. Shut off the game. Shut the lid on the cocktail. Leave it sit for 30 minutes to an hour. Turn the game on. Once the thermistor in the monitor cools down, it'll allow the degauss circuit to operate again.
And any time you move a game or monitor, you'll probably have the same kind of problem - the Earth's magnetic field interferes with the CRT. You notice this phenomenon in cocktails a lot because people leave the lid open, turn it on, then shut the lid, thereby moving the tube relative to the Earth.
And yeah, a degaussing coil is a handy tool to have. Sometimes monitors can get too magnetized for the built in circuit to take care of. Either buy or make one. They're super simple to make - just scavenge the coil from a junked 27" or larger television set, coil it up smaller, and add a line cord and perhaps a switch.
