All the Things You Are
by Robert Sheckley, Galaxy (July 1956); UK edition no. 42 (September 1956), 118-128.
A humorous if inconsequential short story from that once-thriving SF subgenre wherein civilised Earth crews in their technologically advanced ships go rocketing about the galaxy, abjectly messing up first contact with more primitive peoples. Funny enough, without rising to any great heights.
