The Stigg's Helmets

Listen up, buttercup. So, the joke is about The Stigg who is this mysterious race car driver on the show Top Gear. The joke says that he wears helmets under helmets, right? But get this, the last helmet hides a poster of Miley Cyrus! Like, what? It's funny because it's unexpected and makes no sense. The Stigg is supposed to be a tough guy, not a Miley fan! Also, you didn't know that The Stigg's real name is Ben Collins. I bet you thought that was the plot of the movie "Drive".
