customs. Paradoxically, however, by violating these norms and taboos, they help to define the accepted boundaries, rules, and societal guidelines for ethical and moral behavior. They are the only ones who can ask "Why?" about sensitive topics; they use satire to question the specialists and carriers of sacred knowledge or those in positions of power and authority. Vision of thunder beings In Lakota mythology, is also a spirit of thunder and lightning. He is said to use the wind as sticks to beat the drum of thunder. His emotions are portrayed opposite the norm; he laughs when he is sad and cries when he is happy, cold makes him sweat and heat makes him shiver. In art, he is depicted as having two horns, which marks him as a hunting spirit. In some visions, he also appeared as a snow bird, a swallow, a horse, a dog, a night hawk, a frog, or a dragonfly. In popular culture In 2013, Half Acre brewery in Chicago, Illinois, released what they called Heyoka IPA, which became one of their signature beers. It won a silver medal at the Great American Beer Festival in October 2014. Members of the American Indian Movement and other Native American activists argued that giving the name of a sacred figure in Lakota spirituality to a beer constituted cultural appropriation. Half Acre renamed their beer Senita (perhaps after the Senita cactus found in the American Southwest that is depicted on the former Heyoka beer can).
