Loki

In Norse mythology, the trickster god Loki managed to tick off all the other gods by helping to cause the death of Balder and for insulting the other gods afterward. For that, he's said to be tied to a rock with a snake dripping burning venom on his face. His torment is eased a bit by his wife, Sigyn, who catches most of the venom in a bowl. However, when the bowl gets full, she empties it, and Loki can't help but get a face full of venom.
