Place this laugh immediately after the game moment it reacts to, then follow with a taunt-style clip like the bomb has been planted announcement or an enemy spotted callout to keep the strategy-game joke running in one sequence.

This is a very short clip of a woman laughing, about 1.3 seconds long. The laugh lands as amused and a little mocking, a quick outburst you would drop when something has gone wrong for someone else. The facts confirm it comes from Age of Empires II.
