DUFF. Thanks to "Average Joe" I now know that stands for Designated Ugly Fat Friend. Zach, the mule-faced "Joe" who hoped to win Malena's heart, said every pretty girl has a DUFF. A guy has to win over the DUFF to guarantee that the beauty will grant him the seal of approval. On the show, the DUFF in question was actually size 2 Malena wearing a size 24 Mrs. Doubtfire fat suit, pretending to be her own DUFF cousin, Danielle. In the fake fat, she met all four remaining guys -- two of the duds and two of the newly arrived cute dudes -- and then watched hidden camera footage of how the men dished the DUFF when they thought nobody was listening. Big mistake. Zach blew it with his ugly comments about the ugly girl and he was given a one-way ticket back to Palookaville. Malena, meanwhile, locked lips with one of the cuties (again, who can remember their names?) out on a sailboat. Look for her to sail into the sunset with him as her winning choice. The Mrs. Doubtfire twist, by the way, was genius.
