Lots of people who were once alive are now dead. If you had a contraption, let's say a pager, which allowed you to bring one (just one) person back from the dead for a period of 24 hours, who would it be and why?
The pager self destructs straight afterward, and after the 24 hours is complete you lose all of your hair abd go to jail for a year. Do NOT consider this part of the scenario when making your decision, as it is not agaibst the rules. After six months in jail, you also grow a tiny penis out of your belly button.
