I remember watching the cartoon adventures of “Mr. Peabody & Sherman” when I was growing up.  I think it was part of the “Rocky & Bullwinkle Hour.”  Judging from the trailer, the filmmakers are making it a lot more wholesome than I recall it being.

For instance, Mr. Peabody (the dog) and Sherman (the human) weren’t father and son.

Thinking back, I remember it being more of a “master and super-intelligent, passive-aggressive dog” sort of relationship.

This also explains why I vaguely recall Mr. Sherman being an arrogant, know-it-all douche.
