Well, as long as we're doing extreme dad jokes:
Mahatma Gandhi, the great Indian political and spiritual leader, is famous for many things. One aspect of his life that is often ignored is his self-imposed poverty. He walked everywhere, wearing sandals or even going bare-foot across the rocky roads of India. His feet were toughened, and his body was frail and thin with age, constant exercise, and his frequent hunger strikes. Another little known fact is that, due to his strange diet and lack of dental care, he (and the people around him) suffered from chronic bad breath.
One could almost say that he was a super calloused fragile mystic left with halitosis.
