Who gets to get stung?

Levi comes running in the house and says "there is a Bee outside!" Ethan and then Caleb come in right behind him and I hear Caleb saying this to Ethan..."You and Levi need to be the first to get in the house. If anyone is to get stung it should be me. That is my job as the older brother!" Ethan responds with, "Well if you are at school, then I will be the one to get stung. And if we are both at school, then mom will be the one to get stung."
