You've probably Seen It a Million Times during The Golden Age of Animation. Here, a character eats a strip starting at one end of the corncob, along its long axis (takka takka takka), reaches the other end (ding!), rotates the corncob a few degrees and returns to the starting end (kachunk!), repeat. This action mimics typing on an old-fashioned mechanical typewriter with moving carriage. They then continue in a different spot.
Compare Buzzsaw Jaw, where the sound effect is (or at least can be) a buzzsaw.
- Walkers used to run adverts for their "french fries" (basically long, thin potato based snacks) where they were eaten like this (though without the ding).
- In The Girl's Guide to Hunting and Fishing, the narrator says her older brother normally eats corn on the cob this way, but the first time he brings a girlfriend home from college he's suddenly too adult to do it in front of her.
- The image for this page comes from Out of the Inkwell, which features a literal example of this trope.
- On Animaniacs, Wakko did this once, complete with Leroy Anderson's "The Typewriter" as accompaniment.
- Templeton does this in the fairground scene of Charlotte's Web.
- One Porky Pig cartoon when Porky was a farmer had chickens getting into his cornfield and doing this.
- Used in the Disney short Mickey's Trailer.
- Scooby Doo has done this several times with corn on the cob.
- Tom does this with a rib in an episode of Tom and Jerry.
