I grew up on Peabody and Sherman so naturally, in school I always got my dates correct however, the facts were just a little skewed. I subsequently had to read Barbara Tuchman to correct these anomalies.
For those people who need this series here is a quick synopsis. Mr. Peabody, canine of superior intellect realizes that he needs to adopt a boy. In his search comes across Sherman. Mr. Peabody now realizes that boys it is a bit difficult for boys to keep an apartment (no not potty training). Therefore, as a birthday present, he builds a Way-back machine. The machine itself is a "should have been" machine not a "what was" machine and this is where the fun starts.
Although I grew up on Peabody and Sherman, I never really knew how it all started. "The best of Peabody and Sherman" starts off telling how Mr. Peabody adopted Sherman and now everything is in perspective. Oh, maybe with one exception or two this is still my history.
I have great fun anticipating the pun at the end of each episode; then I tried to do one pun better.
Now before you go out in the world you also better read "The March of Folly: From Troy to Vietnam" by Barbara Tuchman.
