Aliens Like Dead Rabbits and Poetry?

To test the existence of aliens, a company in New Mexico sent a suborbital rocket up over Roswell containing the remains of a rabbit, some poetry and some human hair. They were hoping it would be abducted. They were trying to create “a product that would appeal to the extraterrestrials.” Needless to say, the rocket returned unmolested.

What I wonder is, how did they come to decide what would appeal to the aliens? Very interesting. Save this for that story about Keel that I haven’t started yet.
