Mistaken Identity

 is the 123rd episode of He-Man and the Masters of the Universe.

(Ink & Paint DVD booklet description: Whilst enjoying a pleasant picnic in the forest Farin jealously listens to his girlfriend Karil talk the heroics of He-Man. When He-Man appears to battle a Shrieker, Farin concocts a plot to make Karil think he is the secret identity of He-Man. After a very convincing disappearing act Karil is convinced that Faril is He-Man! Overhearing Farin admit to Karil that he is He-Man's secret identity, Modulok captures him. Will the real He-Man be able to save Farin before Modulok's impatience results in the end of the young man?)

Moral
Prince Adam: "Today, Farin learned a valuable lesson about the difference between pretending and lying. Everyone likes to pretend, but when you start pretending like Farin did, that's lying. And sooner or later lies have a way of catching up with you. Eventually no one will believe you, even though you're telling the truth. So remember, tell the truth and be yourself. Cringer: "Oh good. Does that mean I don't have to be Battle Cat any more?" Prince Adam: "No Cringe, sorry. See you next time."
