Cartoonists are working, in general, with the same material: the world, and all the juxtapositions available therein.

Having said that, I’ve done a sea salt gag before.  Most cartoonists can say the same.  What you wind up with, and how it differs from other cartoonists’ take on the same general subject is what separates us all.

Mine was a Buckets cartoon.  The family was dining, and the youngest child says, “This is really good.” and  “What’s the difference between sea salt and regular salt?”  Before the parents can answer, the older brother says, “Fish Poop.” and hilarity ensues.

Now… feel free to google “sea salt” + “cartoon” and see how everyone else did it.  I think you’ll find that Troy did a fine job with his sea salt.
