He just happened to have unusually bristly hair, I guess. But it gave him a very weird look indeed.

I don't know why someone picked that critical moment to shout a warning, because everyone could see it was the kind of argument that couldn't be stopped by anything short of strong-armed intervention. Advice at that point could be just as dangerous as pouring kerosene on the fuse, to make it burn faster.

But someone did yell out, at the top of his lungs. "Pipe down, you two! What do you think this is, a debating society?"

It could have turned into that, all right, the deadliest kind of debating society, with the stoned contingent taking sides for no sane reason. It could have started off as a free-for-all and ended with five or six of the heaviest drinkers lying prone, with bashed-in skulls.

The barkeep made a makeshift megaphone of his two hands and added to the confusion by shouting: "Get back in line or I'll have you run right out of here. I'll show you just how tough I can get. Every time something like this happens I get blamed for it. I'm goddam sick of being in the middle."

"That's telling them, John! Need any help?"

"No, stay where you are. I can handle it."

I didn't think he could, not even if he was split down the middle into two men twice his size. I didn't think anyone could, because by this time I'd had a chance to take a long, steady, camera-eye look at the expression on the Viking character's face.

I'd seen that expression before and I knew what it meant. The Viking character was having a virulent sour grapes reaction to something Average Size had said. It had really taken hold, like a smallpox vaccination that's much too strong, and his inner torment had become just agonizing enough to send him into a towering rage.

Average Size had probably been boasting, telling everyone how lucky he was to be on the passenger list of the next Mars-bound rocket. And in a crowded spaceport bar, where Martian Colonization Board clearances are at a terrific premium, you don't indulge in that kind of talk. Not unless you have a suicide complex and are dead set on leaving the earth without traveling out into space at all.
