A magician, nearing the end of his show, called for a volunteer from the audience for his next trick. A young man volunteers, and the magician motions him up to the stage. The magician then says "Sir, I am going to lay my head down on this table. I then want you to take this sledge hammer, and hit me in the head as hard as you can!"
The young man said "A...are you sure?", to which the magician replied "Yes! Absolutely! Don't worry, this is magic!"
So, the magician laid his head down on the table, the young man lifted the sledge hammer up and struck...
Ten years later, the magician wakes up from the coma and immediately said "TA-DA!!!!"
