June Foray and Johnny Carson
Everyone has to start somewhere. Johnny Carson started in 1951 with a painfully unfunny sketch comedy show called Carson’s Cellar. That, in itself, is hardly Brew-worthy, but this episode posted on Archive.org will delight cartoon fans. The woman who appears at the 4:30 mark is none other than the legendary June Foray, who just celebrated her 95th birthday.
