[2] Foreshadowing this discovery, Harry explains that his "mother was a cold receptacle and [his] father was just a machine," indicating that, unlike the rest of the family, he is a cyborg.

[3] According to an interview with French Stewart on the 3rd Rock from the Sun First Season DVD, Harry was related to/knew an important alien back on the homeworld, and that his position was a sinecure.

The first signs are always physical - he immediately shudders violently, garbles incoherently, then adopts a stance with bent knees and upraised arms, palms forward.

When the message is completed, the exit statement is always "Resume normal functions in three ... two ... one ...", or later "transmission ending in three ... two ... one ...", after which he shudders, performs a dance-like movement, belches, or sneezes.

In the season 4 premiere,[4] Harry opens a transmission line to the Big Giant Head in order to send an overdue status report.

In contrast to what would be expected of someone as weird and apparently unsophisticated as Harry, he seems a very adept lover and often has interludes with those that might be considered "out of his league," though this did not stop him from maintaining a haphazard relationship with Mrs. Dubcek's daughter Vicki.

Their relationship was often interrupted; examples include Vicky's commitment to physical and spiritual purity to the point that she becomes celibate,[5] and her pregnancy with the Big Giant Head's child.

[7] Other affairs have included a well-toned policewoman named Janice (played by Chyna),[8][9] a woman at the laundromat,[10] a single mother (owner of the lost dog Scruffy) and Dick's office assistant Nina Campbell.

In contrast to the frequent exhibition of a total lack of intelligence, Harry at one point speaks fluent French to Dick,[13] and has a natural talent for the arts.

Despite his aptitude with the physical aspects of the opposite sex, Harry seems incapable of fully functioning in a common social situation.

Often he will run off on a mission to right some irrelevant wrong and not realize the "offender" is conceding and will then proceed to take physical and occasionally violent action.
