A Part of the MCU
While Tony and Rhodey are talking/fighting in Iron Man 3, a girl approaches both of them and politely asks Tony to sign a drawing. She’s being followed by a young kid in thick glasses, to whom Tony turns to before signing the sketch. Instead of leaving the kid alone, Tony revealed to him how much he loved him in A Christmas Story.
Those in the crowd who enjoy the classic Christmas film immediately recognized the reference to Ralphie, the main character from the 1983 film. But there are layers to the joke. In the first Iron Man, the actor who played Ralphie, Peter Billingsley, took on the role of a Stark Industries scientist that tries and fails to recreate the Arc Reactor.
