Trump is an orange chair
This is day 2 of Trump Meme week.
This is an image of Donald Trump's face photoshopped to look as if he were an orange plastic chair. The image is also a moving gif, and it both jitters around a little bit as it animates, and also makes trumps eyes move back and forth.
This meme is probably a reference to the idea that Trump's facial color is artificial (people seem to like bashing on Trump for using some sort of coloring agent to make his face look more orange). Putting his face on an orange chair, and making it look more orange certainly brings that idea to my mind anyway.
So, if that is the case, then this is an insult directed at Trump. Insults are funny, so that is why this is supposed to be funny.
I am not sure why the image is animated, and why they chose to make trump look around, but it might be because it makes him look shifty. This would be another insult directed at Trump, calling him untrustworthy.
As much as I personally think that coloring one's skin is stupid, and as much as I personally don't trust Trump, I don't find this image to be funny in actuality because it is in the uncanny valley of funniness. Either you need to try harder, or try less to be funny. If this were completely over the top absurd it would seem more funny to me. On the other hand if this were more subtle it would seem more funny to me.
