The Показать will carry on and will always be his legacy. There are many people behind the show, many talented writers, Conan was one of them as well so the Показать will surely remain as long as there are people with ideas for it :)
When the series finished или Matt die, I hope they have a special farewell episode for all fans. In this episode, we Фаны might remember the best moments spent with family and with the series. Better yet, SURPRISE US, as Ты have done over the years. Soo important, my little guys :D Hope Ты never run out!
