FDA Aspartame table-top approval

In 1981, aspartame artificial sweetener was approved for tabletop use by the U.S. Food and Drug Administration. Its permitted uses included in candy, tablets, breakfast cereals, instant coffee and tea, gelatines, puddings, fillings, dairy-product toppings and as a flavour enhancer for chewing gum, among others. It was first approved on 26 Jul 1974, but objections caused a stay on 5 Dec 1975, and years of scrutiny followed. Years earlier, in Dec 1965, while working on an ulcer drug, James M. Schlatterhad made the discovery that a mixture of two amino acids, aspartic acid and phenylalamine, had a sweet taste. By weight it was about 200 times sweeter than sugar, with very few calories. G.D. Seale marketed it as NutraSweet, a low-calorie artificial sweetener without the bitter aftertaste of saccharin.«

They Cheated

Once two star football players had failed a test, and could not play football in the championship game.
So, after much begging from the coach, the teacher finally let the two take the test again.
They took the test, and turned it in.
The coach and the two students watched carefully over the teacher grading the tests. She checked over the first test, then over the second test. Half way through the second test she stopped and put a great big 'F' on both tests.
The coach was furious and demanded an explanation. She said that they had cheated. 'Why?' the coach asked.
The teacher showed him number six. The coach looked at number six on the first test.
The answer read 'I don't know.' The coach said that it did not prove anything.
The teacher handed him the second test. The answer read 'I don't know either.'
