Around 17:50 mark. Sorry these are just Hulu links I've been posting lately.

Basically, the episode (spoilers ahead if you care - it's a hilarious episode if you love the show, too) has to do with the kids creating a fake religion to save their local aquarium and at the end the IRS agent loves it so much he wants to join. So, they have to put on a whole charade to try to dissuade him from joining, but he ends up finding out the truth after going into a jellyfish tank to get baptized, and subsequently getting stung.

Toward the end, the kids go to the IRS agent to apologize. Here is the quote I thought you guys would find interesting:

(Agent Flanley is sitting at his desk itching his jellyfish wounds)

Man over intercom: Agent Flanley, there are some children here for you. Did you order three children?

Flanley: Hmm. No, I didn't. But send them down.
