A mother, accompanied by her small daughter, was in New York City. The mother was trying to hail a cab, when her daughter noticed several wildly dressed women who were loitering on a nearby street corner.
The mother finally hailed her cab and they both climbed in, at which point the young daughter asks her mother, "Mommy, what are all those ladies waiting for by that corner?"
The mother replies, "Those ladies are waiting for their husbands to come by and pick them up on the way home from work."
The cabby, upon hearing this exchange, turns to the mother and says, "Ah, C'mon lady! Tell your daughter the truth! For crying out loud...They're hookers!"
A brief period of silence follows, and the daughter then asks, "Mommy, do the hooker ladies have any children?"
The mother replies, "Of course, Dear. Where do you think cabbies come from?"

First U.S. gallstone operationIn 1867, the first U.S. gallstone operation was performed by Dr. John Stough Bobbs, known as "the father of cholecystotomy" in Indianapolis, Indiana. While operating on his patient, Mary E. Wiggins (Mrs. Z. Burnsworth) for a suspected ovarian cyst, he found the gall bladder was inflamed and containing structures like "several solid ordinary rifle bullets." He opened the sac, removed multiple gallstones but left the gall bladder in place after closing the defect (cholecystostomy). The patient recovered and outlived Dr. Bobbs. The first account of gallstones had been given as early as 1420 by a Florentine pathologist Antonio Benevieni, in a woman who died with abdominal pain. Jean-Louis Petit performed gall bladder surgery in Europe in 1743.«* |
