MacGyver has had a lot of girlfriends, but his code of ethics requires that he always behaves like a gentleman. One of his first girlfriends is pictured to the right, and she seems to be holding a hamster cage.
They met when she tried to smuggle some Russian jewels into Mac's suitcase. Though that might have seemed dishonest or even malicious, MacGyver always tries to see the good in people.
Whenever girlfriends are around, hilarity ensues.
The women never stay long, though- MacGyver's life is too dangerous to involve innocent parties, and the complications would just leave everyone emotionally bruised.
Though MacGyver seems to enjoy the company of females, it's more than likely that he reproduces via parthenogenesis- which is in keeping with his other super-human lifestyle choices.
