I heard this story this weekend. (a slightly different version, but heck, I didn't want to type the whole thing so I just found this one on the web instead)
Two informally dressed ladies started conversing during an endless wait in the LAX airport.
The conversation turned to children. The first woman, from New York, started by saying, "When my first child was born, my husband built a beautiful mansion for me."
The second woman, a genteel Southerner, commented, "Well, isn't that precious?"
The first woman continued, "When my second child was born, my husband bought me a beautiful Mercedes-Benz.
Again, the lady from the South commented, "Well, isn't that precious?"
The first woman continued boasting, "Then, when my third child was born, my husband bought me this exquisite diamond bracelet."
Yet again, the Southern lady commented, "Well, isn't that precious?"
The first woman then asked her companion, "What did your husband buy for you when you had your first child?"
"My husband sent me to charm school," declared the Southern lady.
"Charm school?" the first woman cried, "Oh, my! What on earth for?"
The Southern lady responded, "Well for example, instead of saying "Who gives a crap?" I learned to say, "Well, isn't that precious"
