Fox grew up in Hartford, Connecticut, and saw his first sword swallower when he was eight or nine at the Eastern States Exposition in West Springfield, Massachusetts.   At around the same age, his father gave him a book about Harry Houdini that inspired Fox to recreate, using spaghetti, the magician's trick of swallowing a key on a string and then regurgitating it. 
Fox began performing magic and comedy while working as a waiter in 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 inspired to begin swallowing swords for "an act people couldn't copy easily."  It took him eight months to master the technique, although he has injured himself on a few occasions.  Fox estimated in 1999 that he was one of twenty professional sword swallowers in the United States, many more than when he began.  
Fox can swallow up to 22 inches of steel.  Besides regular swords, his act has included swallowing a retractable tape measure, a giant screwdriver, and a neon glowing sword plugged into an outlet.  His act also included eating fire until he learned that the chemicals used in the trick could seep into the liver. 
Fox has appeared at venues including comedy clubs (such as Caroline's), casinos, and tattoo conventions, as well as special events such as an Aerosmith album release party.  His television appearances include the Late Show with David Letterman, a 1992 Jonathan Winters television special and a Maalox commercial in which he swallowed light bulbs.    He was featured in the 2003 documentary Traveling Sideshow: Shocked and Amazed by Jeff Krulik. 
In June 1999, Fox opened the Freakatorium, El Museo Loco, a museum of side show curiousities, on the Lower East Side of Manhattan.  In the face of low numbers of visitors and rising rent, the museum was closed in January 2005.  Fox was partly inspired to open the museum by his childhood visits to Hubert's Museum and Flea Circus in Times Square.  His collection includes narwhal tusks, an elephant's-foot liquor chest, a two-headed turtle, a vest owned by General Tom Thumb and Sammy Davis, Jr.'s glass eye.
