. . . Rocky & Bullwinkle & Friends clearly titles this segment of the Season One, Episode One show as "Peabody's Improbable History: Ben Franklin." Nobody who viewed this 64 years ago when it first came out needs a DVD jewel case to remind them that this particular lesson in Western Civilization concerns the discoverer of bifocals, Franklin stoves and electricity. Because the initial introduction to Peabody and his pet Sherman involves a lot of backstory exposition, Mr. Franklin's participation in his television special is necessarily brief. But, when you get down to brass tax, so are lightning strikes.
