I don't allow anyone around to distract me in a regular season game, no way for the SB. I will move my chair directly in front of the TV. My 13 year old son will be with me, and no one else is allowed.
I will get up for the bathroom, or to get a beer (nah, the boy can run to the fridge) and pause the DVR each time just in case.
I was invited to a SB party, by a Packer fan at Christmas in the event it was Pats vs Packers, and my response was
"If you have me in your house for a Patriot SB, we won't be friends when I leave"
