9. Forehead Of Security (Iron Man 3)
When Tony Stark's friend, driver, personal bodyguard and head of security Happy Hogan makes his first video call using a newly acquired tablet to Stark, he doesn't know where the tablet's camera is (what with him being a little bit technologically inept and all that). As a result of his technophobia, he positions himself completely incorrectly in relation to the camera and all Tony can see at the other end is the top half of his face. Tony, being as witty as he is, and playing on the fact that Hogan is indeed his head of security, immediately says "is this forehead of security?"
