Too many variables to say concretely one way or the other.
First, how desperate am I? If it's been a while there's probably only a few games I might turn it down for, like game 7s later on in the playoffs or games in which the cup could be won by the Flames. If it's been a REALLY long time ... well, you know ... we could lose .... and then turning her down would sure seem stupid. (And even if we won there's always highlights or TiVo.) But if I'm not having too much trouble getting laid, the hockey game shoots up in the interest department.
So obviously if the g/f or wife calls and says "blow off the game and I'll blow you off" there's a decent chance i'll tell her to take a hike.
And of course, being ridiculously hot improves her chances.
Finally, if she offers to do it "The Canadian Way", I'll pick the booty call every time.
