The author's a moron. The way Hitler wore his retardostache did not survive.
Not true! *I* trimmed my mustache to the exact dimensions of a "hitler" 'stache when the "fitment" officer at my hospital refused to even attempt a seal test on my respirator unless I "trimmed" my 'stache to his standards.
I did so, and every time he asked me to do anything before, during and after the fit testing, I clicked my heels and said "JAWOHL!!"
He hasn't even asked for me to be fit tested in the 7 years since.
