Nick Pollotta & Phil Foglio: Illegal Aliens (1989)

(This is repost from LJ)

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 )
