"Truth or Daring" is an episode of The Replacements.
When Todd is tired of Riley's truth telling, he gives her "truth salt" that forces her to tell the truth all the time. That's a bad idea when Dick is trying to get reelected for mayor. Meanwhile, Todd gives himself "lie spice" to make his lies 50% more believable, but too much consumption of the salt causes Todd to have uncontrollable lying. Which is also a bad idea when Todd's uncontrollable lying gets him sent to the Corps.
