A farmer needs to get Batgirl, Johan Santana, and George Steinbrenner across a river. He has a small boat and can only take one person at a time. But he needs to be careful. If he leaves Johan alone with Steinbrenner, Steinbrenner will try to sign him. If he leaves Steinbrenner alone with Batgirl, she'll unleash a furious ninja attack.

How does he get all these people across the river in his boat?
