Put Sudden Suspense just before the reveal, then place this clip on the fail itself, and follow it with Nelson's Ha-Ha! once the joke has landed, so the sequence builds tension, peaks on the reaction, and ends with a mocking laugh.
Sobre este som
This is a roughly two-second vocal clip of a man called Bob letting out a long 'ahhhhh' that has been pushed through heavy bass boosting, so the shout lands thick, distorted and much bigger than a normal scream. It feels over-the-top and comic, like a reaction turned up too far, and it works best as a sudden, exaggerated burst of disbelief or excitement.
