the one with the one testicle is a myth i guess. he wasnt of jewish heritage, at least not directly
he fought in WW I and (according to his autobiography) once faced a british soldier unarmed (he was a medic or radio operator anyway) and for some reason the british guy didnt shoot/captured him...
he wanted to study art but wasnt accepted at the academy. had he been accepted, well we dont know.
he tried a putsch in 1924 or so and wasnt charged for treason (judge is said to share equal ideologies) and became a free man after one or two years. had he been thrown to jail for a life-sentence as it was usual for such a crime, well we dont know.
he (or his crew) was the inventor of some movie-marketing things, the frog-perspective comes to my mind. when he was filmed, he looked bigger than he was.
he survived over 30 attempted assassinations.
he wrote mein kampf while in jail after the putsch.
he hated abortions and had fits of rage when he heard about one. obviously nothing was more important to him than an innocent life...
its speculated that his hate on jews was fortified by a jewish girl he was interested him in his youth, but who ignored him.
he had a dog named blonde and it littered during the last days of the war.
he didnt deny jesse owens a handshake. instead he wanted to shake only the hands of germans olympians in 1936, but the IOC told him he should either congratulate ALL athletes or none of them. however, owens later stated that the american president treated him worse after his victories as hitler did.
so much out of my mind, seriously didnt look any of these up so i do not issue a guarantee for any of them.
