The Galaga High Score Gag
Stark clocks a SHIELD agent slacking off playing Galaga on the Helicarrier and makes fun of him for it. The joke doesn't stop there though - the second Tony walks off, the agent goes right back to playing, and if you pause on the screen his score matches the game's existing high score. He was mid-run on the best game of his life and Stark just had to go and ruin it.
