I think they had a “wayback machine”.
“Each episode of “Peabody’s Improbable History” begins with the dog’s greeting, “Peabody here.” The premise each week was to introduce Sherman to real history. For that purpose, Peabody has constructed the WABAC (pronounced “wayback”) machine. The WABAC is a take-off on early computer acronyms such as UNIVAC and ENIAC. The WABAC is a time machine used by Peabody and Sherman to travel back in time and witness various historical events.”
I loved that show!!
