Playoffs?

For most of us follow sports (and more recently reality game shows), even peripherally, we're used to the "season" consisting of a whole bunch of games with a lot of teams, being followed by a smaller collection of games until theirs an ultimate victor or "champion".  Baseball and basketball play series' usually best-of-7, but sometimes best-of-3 or -5?  Always an odd number to guarantee no ties.  Football and NCAA basketball have one-and-done scenarios, but they still funnel the victors through a bracketed structure until there's a winner.  Those are the most common, but there are others - double-elimination, the judges' vote.
It's a concept, once grasped, that you never really think about - until you have to explain it to a 7-year-old.  "But they said last week was the last game?" "Of the regular season, this is the Playoffs." "So they keep playing?" Until they lose a series.  They play one team until one of them wins four games." "And then the season's over?" "If they lose four games.  If they win, they play a different team for four wins."
Don't get me started on the Memorial Cup.
And so it happened last April 19 that I obtained tickets for myself and two boys to see the Spokane Chiefs play the Tri-City Americans - the FIRST PLAYOFF GAME THEY'LL EVER SEE.
Playoffs or not, it was still a school night, so Kim agreed on the following stipulation: home by 8:30, in bed by 8:45.  It is with that in mind that we watched as the Chiefs fell behind, 0-3 after two periods.  With the magic hour approaching, I packed our stuff, turned to the folks behind us, thanked them for tolerating the dancing fools, and said: "hopefully we'll miss the greatest comeback ever." 
Tee-hee!
This season's playoffs are coming up, and he gets it now, so he probably ever have to review the concept.  at least for 20 years or so.
