A shaggy dog story that always blindsides `em, especially when dropped into an unrelated conversation:
You know how Mahatma Gandhi walked barefoot most of the time? Well, a result, he sported an impressive set of calluses on his feet. He also fasted quite often, from both idealogical and spiritual motives, which made his body rather frail, though the spirit was incredibly strong. But when he did eat, it was often very spicy foods, vegetarian curries and the like. And this gave him bad breath, by all accounts. So to sum up, he was a super calloused fragile mystic, hexed by halitosis.
