Can you replace the question mark with a number?

A local priest and a pastor were fishing on the side of the road. They thoughtfully made a sign saying, "The End is Near! Turn yourself around now before it's too late!" and showed it to each passing car. One driver who drove by didn't appreciate the sign and shouted at them, "Leave us alone, you religious nuts!"
All of a sudden they heard a big splash, looked at each other, and the priest said to the pastor, "You think maybe we should have just said 'Bridge Out' instead?"
