Piers Anthony - Prostho Plus (Repost from Livejournal) Dr. Dillingham is a human dentist who suddenly has to treat a denizen of a flying saucer. After the successful treatment, the grateful proto-Greys abduct him and sell him in outer space. Poor doctor gets acquainted with number of (amusingly) alien species and their various dental problems. Eventually he finds himself in the Galactic University of Dentistry and faces its internal politicking. ( Major drilling work for Dillingham )

Spherical alien ship lands on the Central Park of the NYC and teleports a group of test subjects inside to test their suitability to enter the Galactic League. Or that's what they say. The humans just happen to be a gang of street thugs. And the hilarity ensues. ( Not the kind of First Contact the SETI people would probably wish for )
