Place it at the exact frame someone jolts awake, then follow it with an air horn to sell the reveal and a drum sting to close the gag before the next scene starts.

This is the first vocal burst from System Of A Down's Chop Suey!, a roughly three-second blast of raw male vocals yelling wake up over crashing guitars. It feels chaotic and jolting, like a joke landing out of nowhere, with a nostalgic rush for anyone who knows the song. The clip comes from Chop Suey!, released in 2001 on the album Toxicity.
