Never get tired of it
Sam warming up for his ragdoll performance, it's when he dresses up as a doll and acts like a human-sized stuffed toy, letting assisants bend and twist that doll in all imaginable ways, so the audience believes that it's just made of plush or something and then SUDDENLY, at the end of the show, Sam takes off some of the rags and his mask and people cannot believe it that there was a real boy inside all that time!!
And he'll never get tired of seeing people's reactions to it XDDDD
