i.e. Laugh at a joke the developers intended you to laugh at.
Half life Episode 1: I hear a zoombie sound while in the under ground parking lot, I turn around and shoot into the darkness. Alyx appears laughing and says:
"Sorry, I couldn't resist."
I laughed for the next twenty minutes.
Portal: Glados: "Didn't we have some fun though? Remember when the platform was sliding into the fire pit and I was like, "Goodbye" and you were like "NOOO WAAAY" and I was all "we pretended we were going to murder you" That was great..."
In fact all of portal now i think of it.
