A friend once brought one of those "as hot as possible" currywurst, level D (out of A, B, C, D, E, F, FF, FFF - from least hot to hottest). I think I ate two pieces and needed to sit down with a glass of milk?

Either that or some home-grown peppers a buddy once brought and asked us to eat, chewing as much as possible, as a dare. Burned out of my ears.
