Place it near the end of a short villain or war-themed edit, after a setup clip and before a reaction. Pair it with Bomb Has Been Planted for a military punch, then follow with Ah Shit Here We Go Again when the joke turns to the fallout.
About this sound
This is a four-second spoken clip of Sundowner delivering the line about the good old days after 9/11 in his deep, gravelly, menacing voice, with no music or other effects behind it. It feels darkly funny and unsettling because the nostalgia sounds sincere while the subject is anything but innocent. The line comes from Sundowner in Metal Gear Rising: Revengeance.
