In this episode, the dilemma sounds dramatic right away: would you rather travel to any moment in history and never return to the present, or live forever with the constant discomfort of a sharp stone in your shoe?

That quickly turns into a funny but surprisingly deep conversation about time travel movies, changing history, rebirth, being born into a different era, whether any moment in the past was actually worth going back to, and how annoying a stone in your shoe would really be if you could never take it out.
