I think that article restricted itself (believe it or not) to canon character classes - i.e. those published by TSR / WotC. The Houri was from White Dwarf. If we're going to include White Dwarf character classes, then I feel the Houri is easily beaten by the Pervert from White Dwarf's first issue:
"The prime requisite for the Pervert is Charisma, which must be _below_ 9. However, both Strength and Constitution must exceed 12. Alignment can be heterosexual, bisexual or homosexual. Perverts are armour class 7 when wearing black leather armour and using an unsheathed weapon, but suffer a 50% chance of loss of sight per melee turn if weapon is hand held. Suggested artifact: Elven dirty mac. Level 1: Peeping Tom 2: Voyeur 3: Graffiti Artist 4: Obscene Caller 5: Flasher 6: Streaker 7: Groper 8: Pornographer 9: Rapist 10: Pervert"

Not making that up!
