In particular, I think the 2 most pompous characters in TV history are Frasier Crane from Cheers/Frasier and Major Charles Emmerson Winchester III from M*A*S*H. If there were, like, a pomposity olympics, who would win? Frasier Crane, Charles Winchester, or someone else entirely?
I've only seen the first two years of MASH so I can't comment on Winchester.
