Someone asks for something extremely specific/unusual, and are immediate given it likes it the most common thing in the world

The Simpsons: Barney's Yoko Ono-esque girlfriend asks for "a single plum, floating in perfume, served in a man's hat." Moe immediately pulls it out from behind the counter, somehow having it right on hand.

The Simpsons again: Homer asks for the phonebook to Hokkaido, Japan at the library. The librarian immediately pulls it out without searching for it, despite the phonebook for Hokkaido, Japan probably not being a common request at small town public libraries.

The Muppets Movie: Fozzie Bear asks the ice cream guy for honey ice cream for himself, and a dragonfly ripple for Kermit, and gets it no questions asked.

Orson’s Diner from an episode of Garfield and Friends.

I’m quoting from the wiki on this:

“Upon hearing the restaurant’s offer (“If you can order something we can’t fix, you eat free for a month.”), Roy tries to come up with an impossible meal. His orders include moose stew with chocolate sauce, broiled yak nose with green gravy, and an alligator cheese sandwich with very specific details, all of which Orson and Wade are able to serve him.”

Ultimately, they're unable to fulfill Roy's last order of an elephant-foot sandwich with mustard. Not because they lacked an elephant, but because they lacked mustard.

True but the chicken ran away in madness before he could find out that he won.
