Earlier on stage, Kutcher said, "I am not Charlie Sheen" before turning to his Two and a Half Men co-star Jon Cryer and saying, "Jon, I want to tell you something. I do not think that you are a troll." (Sheen infamously called Cryer a troll around the time he was fired from the Warner Bros.-CBS show.)

"Before I present outstanding lead actor in a comedy series… my old category," Sheen said while smiling as the audience clapped, "I want to take a moment to get something off my chest and say a few words to everyone here from Two and a Half Men…from the bottom of my heart, I wish you nothing but the best for this upcoming season."
