Put this clip right after the claim you are questioning in the edit, then follow it with the Ceeday Huh sound as a second reaction, or finish the sequence with the Damn meme sound when the answer proves the doubt was justified.

This is a very short voice clip, under a second long, of a man named Enrico asking 'Yeah?' in a rising, questioning tone. There is no music or other effect behind the single word, just the spoken reply on its own. It gives a listener a feeling of mild disbelief and playful doubt, like a pause before asking someone to repeat themselves.
