Before you're halfway through the door, the litany begins: "Hi, welcome to Pink Flamingos. Today all yellow-glazed ceramic from the 1950s is 10 percent off, except for ashtrays and lamps. Also, all Stengelwear, except for serving bowls, is 5 percent off, and anything with a blue-striped price tag -- but not a green-striped tag or yellow-striped tag -- is 30 percent off, but only until 2:30!" Or something like that. The sale items may change every day, but one thing is constant: The pitch is always relentless, and it always makes us feel like extras in a zany Seinfeld rerun. While most folks visit Pink Flamingos for its well-organized selection of handsome old furniture and near-mint dishware, there are those of us who go there just to hear this astonishing greeting. No matter how often we go -- we've been shopping at Pink Flamingos for years, and have the cool loot to prove it -- we never tire of this zany mantra of merchandise.
