Dennis Miller sounds a lot like Herb Tarleck of WKRP.
WKRP was such a great show. One of my cow-orkers was promoted to Manager of Support a year or two back, but there aren't enough real offices for all the management. So the took out a cube wall, and gave him his own two cube space instead. Amused, I told him he should get some tape to further deliniate his "office". And, since he's in his 30s, I had to explain the Les Nessman reference.
Fortunately, he's a good sport.
