Description: Three panels. The first panel is a picture of a sign on a window with Chinese that tells people to not to throw things out the window. There is a poor English translation on the sign that says "Do not shit in the air like a god." The second panel is D.W. from Arthur glaring at the sign. The third panel is D.W. saying "That sign won't stop me because I can't read!"
You're right, although it looks like they deliberately omitted some prepositions any conjunctions to save space. All the important elements are there, so it should be understandable by native speakers, but I guess that in speech, you would probably have to add a few more words in to make yourself understood a little more easily.
Interesting! Sounds like something that might be difficult for (early) machine translation, maybe before neural networks
