No. Hitler has a Piper mustache.
Or is it a Charlie Chaplin mustache?
Has he tried to annex the Sudetenland?
He kinda does, but Hitler hair would be more disturbing.
If it bothers you, perhaps you could take a marker and make it a Salvador Dali mustache.
I suppose that in a certain light, Piper may indeed resemble a "Dogler" (not as funny as 'Kitler'), but frankly I find a more striking resemblance to Maurice Chevalier...
Actually I think she looks much closer to marty feldman in those pictures.
