There is an old Three's Company episode (I'm dating myself), where Jack Tripper was in a similar conundrum (but at a funeral). He got the earpiece and listened to the game on the radio. You can make this work Phil...just make sure to not yell out when the priest asks "if anyone objects to this wedding, speak now or forever hold your peace."
Similar issue, my wife had the audacity to have her birthday be the same weekend as next years game @ BC.... Guess who is getting a fun filled b-day weekend in Boston next year!!!
