Time Travel Is Impossible

In the prison one day, a prisoner wanted to go back in time to save the people throughout time from dying. The prisoner asked one of the inmates "Do you have a time machine? I want to go back in time and save the people throughout time from death." But the inmate shook his head and said "Nope! We don't have a time machine. We can't go back in time! Time travel is impossible!" The inmate then took out his machete and cut off the prisoner's butt. The inmate then took the butt and put it on the grill for the other inmates. The prisoner lost too much blood and died.
