Just go up there when it is time, usually after they ask if anyone has a year?
He will go up there , wait to see if anyone picks up a year and then just go up and give a few words about how you feel about his achievements. (Like you are proud) u should make a few jokes like he made my life hell but he stuck it out and I am so proud.lol if u want and then give him a big wet kiss and hand him his coin!
