I don’t have any other esoteric David Letterman microphone facts, but another esoteric David Letterman fact is that he was a C student at Ball State University in Muncie, Indiana and has established a scholarship there for incoming students with no grade requirement attached to it beyond being able to have a high enough grade to attend the university in the first place.
He also donated the university’s current communications building.
And a third esoteric David Letterman fact is that he used to be a weatherman on WTHR in Indianapolis before he hit the big time.
No, I am not a David Letterman super fan. I just picked up these facts for some reason. Although being born and raised in Indiana (and currently living there again) helps.
Personally, I can’t think of a single moment from David Letterman’s entire talk show history that tops his cameo in Cabin Boy.
