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.
