An awesome (albeit obscure) entry from a contest on Fark. The topic was “It seemed like a good idea at the time”.

(As an aside, almost all toothpastes contain sodium laurel sulfate, which is what makes it foam when you brush. But it deadens your taste buds to citric acid, which is why drinking orange juice after brushing tastes absolutely terrible.)
