Donald Trump Jr has become a meme

On Halloween Donald Trump Jr, one of the heirs to the fortune that Fred Trump built, shared a photo of his daughter and griped about socialism.

It wasn't long before people began to poke fun at him.

JK Rowling weighed in.

And so did John Legend

And so did most of the known universe.

We have never heard the phrase 'malignant potato' before.

It just went on and on.

Seemingly endless.

Think before you tweet.
