Howard Stern’s comedic sidekick Artie Lange walked off the set of The Howard Stern Show after he got into a very heated argument with his personal assistant Teddy.

Lange began to express his disdain for his assistant of nearly two years because of recent money issues. Teddy retorted by implying there’s more to the job than meets the eye.

As the argument continued, Lange became enraged and physically lashed out at Teddy, but the physical confrontation was apparently defused by other members in the studio.

When Lange returned, he said Teddy would be “dead” had he reached him and he would be in jail.

Stern told Lange to get off the set when he couldn’t promise to control himself around Teddy in the future.
