What happens on cartoons when the screen goes blanc?

What happens when the screen goes blanc on Spongebob square pants?

SpongeBob tends to mess around on television, but as we have yet to learn, he is really a mad scientist, who recently retired after a chemical explosion causing the crusty crab to be rebuilt. Squid ward wasn't much different from what you see on television, but he does tend to go on many dates with some of your tv friends e.g (Sandy,Mrs Puff...) he is very fond of Patric as Patric has been all classy by helping him wou the ladies with his fantsy suits and his Limo and last week he even took a trip to the waters of Los Angles.
Mr Crab is exactly the same except he also works weekly hours as the bank manager.Mr Crab also has taken an interest in television as well and he said to us 'what happens when the screen when blanc on the Simpsons?'
