The funniest scene in Star Wars that I never noticed.

In the scene where the Millennium Falcon has just blasted off from Tatooine, Luke points at a light and says, "what's that flashing?" Watch carefully, and Han Solo slaps Luke's hand away before he says "We're losing our deflector shield. Go strap yourself in." After I saw that, I laughed and had to watch the same scene. I don't know how I missed that one.
