'Monica' in front of an audience

What they saw was Monica, the tenant that was living with them in a small two-room apartment Walter had rented to her.

But what surprised them the most was the yellow bodysuit she was wearing!

On this sight, some of the attendees instantly felt the blood rush into their pants!

"Woah, Monica? What are you doing here?" Peter asked.
"And why that outfit?" Jacob added.

Now the apparent Monica opened her mouth and said "Actually, I am not Monica!".
