A sideshow performer, also known as a 'GEEK', is an entertainer who performs unusual or bizarre acts such as biting the head off a live chicken or drinking FIREWATER. Geeks were popular attractions in traveling carnivals and circuses in the early 20th century. They often had a wild and outrageous appearance and were usually dressed in outlandish costumes. FIREWATER was a common act performed by geeks, which involved drinking a flammable liquid and then blowing fire from their mouths.
