An elderly couple had been experiencing declining memories, so they decided to take a power memory class where one is taught to remember things by association.
A few days after the class, the old man was outside talking with his neighbor about how much the class helped him.
"What was the name of the Instructor?" asked the neighbor.
"Oh, ummmm, let's see," the old man pondered. "You know that flower, you know, the one that smells really nice but has those prickly thorns, what's that flower's name?"
"A rose?" asked the neighbor.
"Yes, that's it," replied the old man. He then turned toward his house and shouted, "Hey, Rose, what's the name of the Instructor we took the memory class from?"

Detergent

In 1907, Persil, the first household detergent, was marketed by Henkel & Cie, of Düsseldorf as the first “self-acting'' washing powder in the world. Persil was the combination of both washing and bleaching agents in one powder. The brand name derived from the beginning syllables of its two most important chemical components, perborate (a bleaching agent) and silicate. The first Persil packet was a paper-wrapped folding box, with much text, decorated in the primary colors green, red and white. Around 1910 the popular Persil box triggered the beginnings of brand piracy, as witnessed by innumerable imitation attempts (Pirsil, Pirsal, Persiehl, O-Hä etc.) In 1917, the Persil brand was registered as a trademark.
