In its pilot episode back in 2005, “How I Met Your Mother” introduced viewers to what might very well be the biggest misnomer in television history — the grumbling teens finding out how their parents met is, in fact, the show’s biggest artifice. Throughout the show’s six seasons, the disembodied voice of Future Ted (Bob Saget) has actually spent very little time over the past six years dealing with the exact chronology of events which brought the eponymous “Mother” and himself together.
