Jerry

Slim is a minor character in The Powerpuff Girls, at waiter at an upscale restaurant.

Season 1
Jerry was the waiter for John Utonium and Melanie Reenie during their date. Utonium ignored him and jokingly asked him to pour water on an eavesdropping David Wilson. Utonium noticed a man, Quinn, watching him and wrote instructions on a napkin and handed them to Jerry.

He read off coded messages from the napkin to Utonium and secretly explained that he noticed the man and that there was a back exit they could use near the bathroom. Utonium thanked him and took Reenie to the exit.
