Donald Trump writes an academic paper:
How funny Trump is depends, naturally, on who you, the reader, might be. He's not funny if you are an immigrant to the US or a Muslim, and he is certainly not funny if you happen to belong to that half of humanity which he judges by butt shape and tit size. But for all of us laughing at his utterances is also tinged with that small frisson of fear, when one thinks of those famous fingers on the nuclear button.
Maybe this is just gallows humor.
