Synopsis:
Professor Lang discovers several artifacts within a lost city. When he returns to Smallville his translations of the ancient inscriptions is questioned by the faculty of his school, and they force him to prove their validity in order to get a promotion.

Lang has not had enough time to translate everything, so Superboy pretends that one of the artifacts that the professor has translated switches his mind with Krypto’s. Superboy acts like a dog for a few days in order to convince the members of Lang’s school board. When the professor has completed his work, Superboy drops the act and claims the effect has worn off.
