Sideburns...S

Are they the RC Cola or the Dr. Pepper of facial hair - i.e. a third rate pretender or a surprisingly refreshing alternative to the beard or mustache?

Pictured here is General Ambrose Burnside, whose name became a style of facial hair, just like Anthony Van Dyck, Giuseppe Verdi, Italo Balbo, Charlie Chaplin, Giuseppe Garibaldi and Arthur Soulpatch.
