Sure you could tell him that if you like. Before you do, be prepared to potentially hang out with him on active duty a little longer. You see, that type of behavior would probably land you another 3-5 weeks of duty. The impact could be corrective training that lasts until your departure, a delay in your separation for an Article 15, or (depending on how you choose to express yourself) you might enjoy a longer-than-anticipated stay while you hang out for a court martial.
That said, why would you even want to bother? You have made it this far, be professional and exit the service with your head held high. In the end the only person who loses when you make a poor choice is you.
