Gypsy matchmaker

The Gypsy Matchmaker is an NPC that came with The Sims 2: Nightlife Expansion. The Matchmaker can summon a blind date for you (your compatibility with your date depends on how much you pay the Matchmaker), or sell you a cures for Vampirism, Lycanthropy (Pets), or PlantSim (Seasons). The Matchmaker is an unplayable NPC (barring hacks), but can be befriended and fall in love with a controllable sim. However, the only socializing actions allowed with the Gypsy Matchmaker is under the Talk, Flirt and Influence menus (which is much more limited that the Influence menu of a non-NPC Sim).
