Artie Lange, a mainstay on the Howard Stern Stow, resigned Thursday after an argument and subsequent outburst at his personal assistant on the air.

Lange, who became a member of the show in October 2001, was seen disputing with his assistant in the hallways off the air. Once Stern found out about the dispute, he invited Lange's assistant Teddy to discuss it on the air.

The argument began with Lange's issues with Teddy over money, then discussed travel accomodations Teddy, known as "Teddy Microphone" to the staff, made for Lange to Amsterdam.

As the argument ensued, Lange physically lashed out at Teddy. The scuffle was broken up by staff members, but Stern denounced Lange's actions.

Lange, who has a similar incident on air in the past, said he could not guarantee not acting out in this manner in the future. Stern replied, saying he cannot have Lange around with the potential of another physical outburst.
