John Edward Szeles (September 9, 1958 – February 22, 2022), better known by the stage name The Amazing Johnathan, was an American comedian and magician. His act was mostly composed of hijinks, interaction with one specific audience member, and a few legitimate magic tricks. From 2001 to 2014, he was a year-round headliner in Las Vegas. Self-described as the "Freddy Krueger of Comedy", Szeles performed wearing his ever-present headband, and his shows frequently used gore; for example, pretending to suck on his own hanging eyeball, cutting his wrists, and skewering his own tongue. He was also good friends with fellow performer Criss Angel and helped him perform a variety of illusions, most notably during three guest appearances on Angel's Mindfreak.
