When Robert Sheckley came on the scene, he produced a lot of amazing stories in a short period of time. This collection contains some of those he wrote from 1953-1955, and they're still just as clever and amusing now (to me, anyway) as they were long ago. A couple of these are favorites of mine. "Skulking Permit" is about a planet with no crime, where the citizens try to create some because they wouldn't want their earthly visitors to be disappointed in them. "Ask a Foolish Question" is supposed to have had a small influence on Douglas Adams. "The Accountant" is about the perennial problem of a father disappointed by his son's choice of profession.
If you haven't read Sheckley, you've missed out on some of the most entertaining short stories of the great era of the SF digests. Check him out.
