There is an episode of “Leave It To Beaver” in which Beaver gets a haircut. The barber is Floyd, the same character he played on the Griffith show.
I just watched that episode of Leave it to Beaver last weekend. I made my older 30+ kids watch it because I thought it was the funniest episode ever. But the barber was not the one who played Floyd the barber on Andy Griffith unless they changed barbers somewhere along the way.
