Ed Asner

From OAPedia.com

Ed Asner is perhaps most famous for his portrayal of the character "Lou Grant" on The Mary Tyler Moore Show. He appeared on the February 23, 2005 Opie and Anthony show at the Los Angeles at the site of the World Poker Tour Pro Am, which Anthony was taking part in. Asner gave Opie, Jim Norton, and Joe Rogan a very politically charged interview, which ended rather abruptly when Opie told him that Ben Sparks, the producer, gave him a signal that the interview had to end because he wasn't funny enough. Asner proceeded to call Opie "The Destroyer" and lambasted him off mic. Allegedly, an ethnic slur was uttered.

Asner also has an ongoing feud with Sean Hannity.
