When it's Okay to Jump on the Bandwagon

I work with a lot of people, some of whom are even hockey fans. Among these are a father and son pair who have traditionally both cheered for the Ducks. As the Kings advanced deeper in last year's playoffs, the father started to change his allegiance, even going so far as to reference the Kings in the first person ("our power play", "Saint Louis can't stop us", etc.) which is usually the sign of the either the die-hard or the delusional.  That probably made for some awkward drives home.
