The thing is that according to Yeshua (Jesus) Christians are forbidden to swear any kind of oath. Maybe the dummy should read the fairy tale instead of swearing oaths on it.
Matthew 5:34-37 (CEV) = "34 But I tell you not to swear by anything when you make a promise! Heaven is God’s throne, so don’t swear by heaven. 35 The earth is God’s footstool, so don’t swear by the earth. Jerusalem is the city of the great king, so don’t swear by it. 36 Don’t swear by your own head. You cannot make one hair white or black. 37 When you make a promise, say only “Yes” or “No.” Anything else comes from the devil."
