Ok so Doug is helping me play a joke on Natalie (the wife) and this involves the dunk tank. I have a personal message already set-up stating that since we are the new comers we have to participate in the dunking. Before the wife and I arrive at the library I am going to text Doug and from there he will wet his hair making her think he did the dunk tank, and that's were everyone comes in we start telling her if she brought extra clothes, if she brought her makeup etc... And from there we will let her on the joke.. If anyone has any ideas that can help me let me know. thanks everyone..
