 When the DeLorean goes back in time for the first time, it stops by  crashing into a barn, which we soon learn belongs to a farmer named  Peabody. We know this because as the DeLorean speeds off the  property to escape being shot, we see buckshot shatter the mailbox  bearing his name. Farmer Peabodys son is named Sherman. Sherman was  the name of the little boy time traveler in each of the "Peabodys  Improbable History" sections of Jay Ward (I) (qv)s cartoon show,  _"Bullwinkle Show, The" (1961)_ (qv). The dog who "owned" Sherman  and the time machine was named Mr. Peabody. In another reference to  that show, the first character to travel through time is the dog,  Einstein.
