The Last Laugh

The visitor from Mars was a first-rate howl. Earthmen reckoned he was endowed with all the qualities of all the greatest clowns in the history of Buffoonery. Often though, the distance between humor and terror can be too short to be funny.
The scarred rocket rolled down street canyons away from United Nations City, wheeled toward Madison Square Garden between jam-packed, crazily-cheering millions of citizens from every nation on Earth.
Confetti snow drifted in colorful storm, wild faces shone through drifts of spiraling streamers. Signs floated everywhere. Neon signs blinked off and on. Signs floated from balloons across the kleig-lighted sky. Welcome hero signs. And even signs shouting:
WELCOME TO EARTH—ZEKE!
They spelled the name wrong, Johnson thought with some dismay. But that's the way it sounded, he decided, when I radioed in ahead that there was a Martian with us.
Spelled ZEKE, the name scarcely projected the dignity of the name's sound in Martian language. But, in thinking about it now, Johnson realized that it was the only way it could be spelled or pronounced in English.
This seemingly insignificant fact bothered Johnson now. He felt a growing uneasiness. The Martian was largely his responsibility, he felt. It had been Johnson who had spent most of the time on the first visit to Mars with the few Martians left in that one isolated mountain village, learning their language and ancient, conservative, almost static culture. Being an anthropologist, among other things, it had been natural for Johnson to have manifested this particular interest.
Johnson had also been the one to suggest that perhaps Zeke might like to pay Earth a visit.
Zeke had readily agreed, but now Johnson was beginning to wonder why. In six months another rocket would go to Mars and Zeke could go home, but meanwhile—Johnson suddenly began to wonder about the possible ramifications of a Martian's first visit to Earth.
He had radioed ahead about the Martian but had given no details. The world awaited its first look at a Martian, the expectation overshadowing their hero worship of Captain Stromberg, Atomics Engineer Hinton, and Professor William Johnson—the first successful navigators of deep space.
