The spectator is shown 12 cards, which represent the 12 hours of a clock.
The spectator is asked to think of any hour from 1 - 12.
For example they pick 7 o'clock.
You count down from 12 to 7 o'clock and then ask if they would be surprised if their time was on the prediction?
You turn over the prediction and it states 'Your Time', a gag.
However, when the prediction is removed, it matches the hour the spectator selected.
For the CRAZY ending, the rest of the cards are turned over and they are completely BLANK, now that's TIMELESS!
