I believe free will is real, but that your joke doesn't constitute any sort of proof. I will give one response to your joke. Saying that you are giving up your free will and letting someone else tell you what to do has zero bearing on whether you are really giving up your free will or not. Any sort of proof that we have free will can't go in the agreement camp. I think we can only say that free will is at least a perceptual reality. Some choices commonly held to be actions of our will are demonstrably determined. Free will must act within the bounds of a variety of deterministic laws that control all matter.
