Your story reminds of a research seminar I attended where one of my finance professors pointed out a flaw in the economic argument made by the speaker. The speaker, who is a noted finance researcher, confidently said that the professor was wrong because a paper by A, B, and C had shown otherwise. My prof replied that perhaps the speaker was misinterpreting A, B, and C's results. At this point, another professor chimed in and gently informed the speaker that he was talking to B who is a co-author on the paper by A, B, and C! I don't remember the reaction of the speaker much but I recall that he handled it in a dignified way and backtracked from his claim.
