"You are not calling a duck!"
- — George Feeny
At first the call simply consists of yelling "Feeny!" repeatedly, but in Friendly Persuasion Eric turns it into a sort of song and dance. This version consists of him making claw-like motions through the air while saying: "Feeny? Fa-fa-fa-fa-feeny! Feenay! Fee-hee-heenay! Yow! Hey, hey, what? Whatcha-what-what-what! Hey-ey! Yow! Hey-ey-wow-yay! Yow!" Further variations include him repeatedly yelling "Feenay!", possibly tossing in "Fee-hee-heenay!" for good measure.

- In Brave New World, Eric gives Mr. Feeny an Eric Doll that makes the Feeny call, to remind him of Eric after he is gone. (Side-note: actor Ben Savage who portrays Cory Matthews, can be seen in the background in the opening moments of this scene, evidently fighting back his emotions as this was the final episode of the show).
