Although I think I could evade the bulls due to my cat like reflexes, the possibilty of a photo like this including me is the main reason I would never do this.
I can just hear the family at Thanksgiving, "Did you see the picture of Dad getting a bull's horn up is a$$?"
Could be worse, in some other celebration bulls carry fire on their horns... then the thanksgiving moment would be, "do you know why daddy always sits on ice?"
