Mr. Peabody and Tim

Mr. Peabody was a bit before my time. My familiarity with the character extends to a bizarre one-line cameo ("Quiet you!") in an old Treehouse of Terror episode of the Simpsons, and not much further.

rabid Peabody!

It's shame they had to cut open Mr Peabody's head after he killed Sherman

Mr. Peabody!

What ever happened to him and his pet boy?
