Having lived with a woman in the late stages of pregnancy, I can say this would be plenty reason enough to finish up early:

A pregnant Steelers fan is not letting the birth of her baby get in the way of the Super Bowl celebrations.

She convinced her doctor to induce her early, so she'll be home in time to watch the Super Bowl with all of her friends.

Yeah, that's it. She just wanted to watch the ball game. Getting rid of a squirming multi-pound mass that's been stomping on her insides for the past few months doesn't factor in at all.
