Johnny Thompson (born c. 1934) is a Polish American Las Vegas illusionist who performs under the stage name The Great Tomsoni with his wife, Pamela Hayes. They have a comedic slapstick act with the well-dressed Thompson and his gum-popping assistant, Pam, performing illusions while enduring a series of mishaps. Within the magician community, Tomsoni is considered a virtuoso, widely known as a mentor and teacher of magic, and a creator of tricks, as opposed to simply a performer. He has worked behind the scenes with magicians such as Penn and Teller, Lance Burton, and Criss Angel. In 1999, he was awarded one of the highest honors in the magician community, a Masters Fellowship with the Academy of Magical Arts.
Along with his wife Pamela Hayes, he performs a slapstick comic magical act in which he plays the role of a dapper but buffoonish vaudeville gentleman, with a gum-popping assistant, and they endure various mishaps during their performance. One of his trademarks is producing pure white doves on stage, which are trained to play along with the act once they have appeared.
He has been featured on many episodes of Criss Angel's Mindfreak, the "Hair" episode of Penn and Teller's Bullshit!, and the film The Aristocrats. His wife and assistant, Pamela Hayes Thompson, was featured in the film Women in Boxes about magicians' assistants.
