Peabody's Improbable History Is part of the Rocky and Bullwinkle show. It is about a talking dog who adopts a boy named Sherman and they go back in time with their "WABAC machine".
Mr. Peabody is a gifted Anthropomorphism dog who lives in a penthouse in New York City and there, he raises his adopted human son, 7-year-old Sherman, and tutors him travelling throughout history using the WABAC machine, a Time travel. They visit Marie Antoinette in Versailles, France during the French Revolution in 1789. Getting caught in the Reign of Terror, Peabody is nearly sent to the guillotine to be executed by Maximilien Robespierre, but escapes with Sherman through the Paris sewers.
Mr. Peabody, the smartest dog in the world, and his boy Sherman host a zany late-night comedy show broadcast from their swanky penthouse in front of a live studio audience. Anything can happen in this show jam-packed with exciting segments, great musical acts and very special guests like outrageous neighbors and hilarious time travelers they meet with the WABAC machine!
