Many UR readers have had the priceless educational privilege of growing up behind the Iron Curtain. These readers will identify Professor DeLong's tone at once: it is the tone of the Soviet humor magazine Krokodil. I will take the liberty of Anglicizing, and call it "crocodile humor." Extremely educated readers may also be familiar with the Nazi variant, as found in Der Stürmer and the like. The material is different, of course, but the tone is unmistakable. We'll hear a good deal more of it in the next four years.

Crocodile humor is the laughter of the powerful at the powerless. It is not intended to be funny. It is intended to intimidate. Those who laugh, as many do, are those who love to submerge themselves in a mob, feel its strength as theirs, chant and shake their spears as one. Professor DeLong and his tribe have certainly backed the strong horse in our little moment of hipparchy, and even those of us who mock the rite must respect its anointed, in the ancient way, as conquerors. A reactionary always respects strength. But the powerless, too, can laugh.
