My priest duo was originally Ludacrits and Ludacritz, eventually some jealous bag of dirt reported the names and Ludacrits was changed to Ludarits.

My three warlocks are Ludarots, Ludarets, Ludaruts if I remember correctly, to play together with Ludarits. The shaman quartet is Shamadee, Shamadoo, Shamadaa, Shamadii - causing headaches wherever they go.

The mage trio I play with a friend is nuts, Aquá, Aquå, Aquà (really hard to distinguish with the default WoW font).

The tauren hunter duo, one black and one white, is Crockett and Tubbs.

If I had ran a warlock duo instead of a priest duo originally, it would have been BenAfflock and some reference to J-Lo.
