I may be going out on a limb here, but I think the foreign-language-textbook-cartoon is one of the most underrated art forms. Just look at the examples below – the options for what these people could be saying are just endless.
Each vingnette featuring some aspect of the lives of these fictional foreign-language speakers is just begging for some obnoxious caption or subtitle. Knock yourself out and see how much fun you can have.
On the other hand, some images are just scary. Who wants to learn the words for body parts from a demonic baby? Run away!
