Ethan here with a funny Halo story.

On the level "Truth and Reconciliation" on Halo: Combat Evolved I was finding my way through the Covenant ship when a door opened to a launch bay.  Seeing an army of elites and grunts waiting for me beside the airlock I threw a frag grenade.  As they scattered I saw one elite in particular look down at the glowing explosive, yell something, turn and jump away...

...only to fly right out the airlock into space.
