Artie Lange, has apparently quit the Howard Stern Show... again.

This is the second time Artie has threated to walk away from Stern. As a matter of fact, Lange threatened to quit by the end of last year. Maybe this is just his delayed response.

Evidently, this all started when Artie and his assistant Teddy got in a knock-down-drag-out in the hallway. Stern jumped in and dragged the two on air. The fight got so bad that Artie had to be held back to avoid hitting Teddy and going to jail.

On Thursday, Lange resigned and Stern accepted. Perfect timing too, because Howard isn't live on Fridays and is on vacation next week.
