No one was spared; Clarence Thomas, Ted Kennedy, Johnny Carson, Madonna were all brutally satirized. I remember two guest stars in particular - Rabert Vaughn and Larry Linville (from MASH) with a "what the hell am I doing here" look on there face while Stern flew through horribly acted, poorly organized; but incredibly hilarious skits.
I remember Nichelle Nichols of Star Trek fame pulled out of the show literally at the last second and avoided lending her name to a Star Trek spoof that was borderline pornographic - an unflustered Stern pulled a group of black women to audition to take her place.....and put the auditions on the air! The show was so controversial - rumors of cancellation came and went on a weekly basis. So what did Stern do? He orchestrated a fake cancellation on April Fools Day and started the show with a made up sports talk show. This prank became all the more poignant a few months later when the show was canceled for real.
I guess you can find episodes of this show on E-Bay, but according to Stern, the rights have been passed from company to company over the years and the odds of releasing the show on DVD are about zero.
Not for everyone - but this show was a shooting star - burned out fast and was over almost as soon as it started.
