Place it right after the fake number appears on screen, then follow it with Wrong Answer Game Show for the failed reveal and Oh My God Wow when the group reacts. Keep it as the verdict in the middle of the exchange, not the opening line.

This is a brief, roughly one-and-a-half-second spoken outburst in which a voice delivers the line with blunt disbelief, as if calling out a number that cannot possibly be real. It feels exasperated, dismissive and sharply funny, landing like an instant verdict on something fake. The delivery is direct and unpolished, which makes the disbelief feel immediate rather than performed.
