Like many, many people, I have seen the Avengers several times. Several.
Remember that little monologue that Tony gives to Loki at the top of Stark Tower? Where Tony is listing all of the Avengers and there's the whole spine-tingling "you can be damn sure we'll avenge it" bit?

GLOW STICK OF DESTINY.
How had I missed that before?! I rewound, rewatched, and then rewound it again. Checked with others to make sure they heard it, and then just laughed. By far one of the best quips I've heard.
