~jokingly~ What do I do if I accidentally broke the space time continuum?
Wait for The Doctor to appear with his sonic screwdriver.
Repair it---use duct tape, glue, and bailing wire.
Call Mr. Spock, he can fix it.
Go to the Space/Time Out Corner and THINK about what you've done, of course. Tsk!!
Put it back on the shelf, behind all the others. By the time they discover that it's broken, you will be long gone.
Look for Cerebrogasm when you break it ! He'll have graphs and charts and a whole computer program developed to explain exactly, and I mean EXACTLY, what was going on when you broke it . :)
