I'm a fan of C-Span's founding father Brian Lamb. In beltway talk he's known as "the Spinx" for the poker-face he shows when callers say things like, "Clinton killed, he will kill again" or "the FDA wants to ban NiQuil and it's the only thing that puts me to sleep". Brian lives a sort of 19th century life; he rises at 4am and reads every major newspaper in the U.S., Europe & Asia before having a tumbler of whiskey during open lines at 7am EST. He is preternaturally calm but then again who wouldn't be if you're unmarried, have a cush job and a 58-year old's sex drive? Mr. Lamb is known for his exceptional sense of humor - he once peppered a guest with questions like, "What do you write on?" He's also been known to stretch the truth, like when he referred to Hillary Clinton as a United States Senator. (Wait, ouch….she IS a senator).
NB: Much of the above, of course, is blarney.
