He was released following the investigation when it was determined that the item was a prop from a commercial, and that an assistant had packed his bag for him.
On February 4, 2009, Knoxville explained on The Howard Stern Show how he tore his urethra during a stunt for Nitro Circus explaining how he had to flush it twice daily. He said this was done by "sticking a tube into his penis all the way up to his bladder" referring to the practice of catheterization, (10–11 inches). Knoxville said the process prevented scar tissue from forming.
