The Greaseman

From OAPedia.com

Doug Tracht, AKA The Greaseman is a radio DJ who was fired in 1999 after making a joke about blacks being dragged behind trucks, but has since returned to the air. After Opie and Anthony got in trouble for the Sex for Sam 3 incident, Greaseman appeared on Fox News criticizing O&A. Anthony does a spot-on impression of him.

Greaseman is known for unnecessarily rolling his R's, goofing on non-whites, and using a hackey radio voice. Some of his catchphrases include "Linger longer", "Bone dry", "Slingin' lead" and "Waddle doodle".
