25. Jonah Hill – scarred arm
He might be one of Hollywood’s most popular funnymen, but there’s one thing Jonah Hill doesn’t ever joke about.
His scar is no joke
Keep a close eye on Hill in the likes of Superbad and Maniac, and you’ll see on his right arm is an unmistakable scar.
The scar is the result of a teenage misadventure, which viewed from afar, looks like a burn.
