I think it is true, that you sometimes come up somewhat ... well ... I dunno ... maybe clumsy? - no, that ain't the word. out of context / over the top? I really am not sure how to explain. over-sophisticated?
I think the words you're looking for are self-important and lacking a sense of humor about himself.
For gawds sake Olaf, just lighten up and everyone will just love you. You'll be irresistible. Really.
