Place it just before the reveal, with the doubles already visible, then follow the entrance with a game show correct answer sting to confirm the real one, and save an air horn for the moment they take centre stage.
About this sound
This 2.7-second clip is Eminem rapping the hook asking the real Slim Shady to stand up, in a quick teasing delivery over a springy backing beat. It feels funny and confrontational, like calling one person forward while the rest stay seated. It comes from The Real Slim Shady, Eminem's 2000 lead single from The Marshall Mathers LP, where Slim Shady is his alter ego.
