Get the Josef Mengele mug.
A satanic, sadistic scumbag who managed to evade authorities for over 3 decades hiding in South America until he passed away, untouched.
Josef Mengele was a sick, evil Nazi doctor who avoided authorities for a hecka long time by escaping to Argentina, then Paraguay and eventually Brazil, using several aliases while on the run for 34 years until he drowned while swimming, via a stroke. In my opinion, his heinous acts, accompanied by his fugitive life has caught up with Mengele with his death.

a sick, twisted, demented, insane, psychopathic, fucked up, nazi motherfucker. nicknamed the "angel of death". he is the basis for the fuckin awsome S L A Y E R song "Angel of Death". he did sick ass experiments on jews at a concentration camp in auschwitz.
auschwitz, the meaning of pain
the way that i want you to die
slow death, immense decay
showers that cleanse you of your life
forced in, like cattle you run
human mice, for the angel of death
four hundred thousand more to die
S L A Y E R rulez.
