Fox began performing
magic and
comedy while working as a waiter in
Saint Petersburg, Florida. He learned sleight-of-hand in the 1970s from
Tony Slydini, an Italian magician known as
"the Master of Misdirection". In his early twenties, Fox was performing in
Boulder, Colorado, when he heard that his act had been stolen by a competing magician. He was featured in the 2003 documentary
Traveling Sideshow: Shocked and Amazed by
Jeff Krulik. He occasionally worked as a
consultant for other sideshow artists. Image:Sword-Swallower Johnny Fox.jpg|Johnny Fox sword swallowing at the Maryland Renaissance Festival in 2006 File:Johnny Fox performing at Maryland Renaissance Festival - 08.jpg|Johnny Fox performing
