In case you missed it, Valve's online store now stocks a test subject's best and happily unsuspecting friend, the Weighted Companion Cube. Made of soft and sufficiently flammable polyester fiber, the demonically dimensioned (6" x 6" x 6") pal can be introduced to yourself or a "real" friend for $29.95. Unlike those irksome human mates you may or probably don't have, the companion cube will never complain when you hog all the cake or inevitably murder him.
