Eel joke

Last night, I stepped on a viper and it turned around and bit me. After a while, the snake twitched all over, foaming at the mouth and then died. I spat at him and disdainfully said to him: I have drunk melamine milk, white flour, fried dough sticks made from waste oil, red-heart duck eggs marinated in Sudan, artificial eggs made from chemicals, ricefield eel fed with birth control pills, braised pork soaked in formalin, moon cakes made from old ingredients, white wine rich in methanol, cigarettes with excessive heavy metals, and seriously polluted water since childhood.
