Likewise, one of those edible crayon creators, Frank Manteau, told Task & Purpose that when he was in the Marine Corps in the 1990s, the joke about eating crayons didn’t exist yet.

Eating crayons, often associated with toddlers, odd behavior and a dated understanding of autism, became shorthand for calling someone simple-minded as early as the year 2000.

The edible (and writeable) crayons have a rectangular shape so kids, and Marines, know which ones are safe to eat, and which are not.

When Frank Manteau joined the Marine Corps in 1995, the "eating crayons" joke didn't exist quite yet. He was used to the more timeless derogatory words, such as "jarhead" and "bullet sponges ...

Crayons Ready-to-Eat officially launched in 2018, Task & Purpose first reported. Manteau said that when he served from 1995 to 2002, Marines were not called crayon-eaters.

This is not to say that Marines are vampires, but, as far as crayon flavors go, the blood of the enemy is pretty sweet. We think Marine Gens. Chesty Puller , Jim Mattis and Smedley Butler would agree.

That’s why Tashina Coronel, a Marine Corps veteran and the owner of Okashi Sweets, decided to start selling crayons Marines could actually eat. She also threw in edible glue for good measure.

With all the crayon-eating memes and products, it makes one wonder if the crayon-eating joke will ever get old. Uriarte doesn't think it's going away any time soon.
