Pretentious fuck whom many people find amusing in a "I'm semi-conscious because its five past fuck-knows-what-hour and hey here's some late night TV - oh this guys funny, but only because my brain is concentrating most of its energy on digestion" sort of way. Characteristics of the Letterman include corny
predictable jokes, cabaret music, boring celebrity
guests and a good old wank. Apparently the Letterman likes his studio nice and cold, so when a journalist asked why it was so cold in there some PR person was all grovelling-like "because Letterman likes it that way" - what sort of self-centered fucking bullshit is that? Do you control the fucking atmospheric temperature now as well as the airwaves between 3 and 4 am?
