The Lyin' King - S1.E4

Dr. Bindlebeep prepares to give a speech about truth in the media that evening and uses his captive family audience at the breakfast table to practice the speech and to preach about truth in general. Of course, Dr. Bindlebeep leaves out the fact that he sneaks donuts, during his morning walks and therefore often lies to Norma. In any event, the family is sent off with a lecture on telling the truth, but Roy apparently doesn't listen. Driven by his desire to see a PG-13 movie, the twelve year-old tells a series of lies that sink him deeper and deeper into deception. While he does manage to see the movie, he realizes the consequences of lying can be far greater, than it might seem.
