One of two things happen:

(1)  It’s a close game, which means that you sit there watching for an hour before it gets exciting in the last quarter, or (more likely) the last minute

OR

(2)  It’s a blowout, in which case you sit there waching for more than an hour just waiting for it to end.

I think I watched my first televised basketball game in its entirety the other night — Game 6 of the Celtics-Lakers matchup.

Glad the Celtics won of course.  But it was a #2.
