Yeah, that's a bull giving a matador the ole "Timothy Dalton at the end of Hot Fuzz" treatment. Horn right up the windpipe, right out the mouth. Don't worry, the man is still alive... somehow, but he's described as being in critical condition. I'd say so. As one of the posters of Deadspin so astutely pointed out, I bet it was easy to intubate.
Normally there would be cause for consternation and condolences for the poor man getting a horn in the jugular. But, seeing as how he was engaged in slow, ritualized, artistic animal murder, it's only fair that the bull gets to put points on the board as well. Fuck him. Yay bull! Don't mess with mother nature, Spain.
And just in case you were wondering... yeah, that photo does enlarge. Click to embiggen.
