My dear old uncle was rather eccentric when it came to being tight with a nickel. He had plenty of money because he never spent it. Never bought anything 'new' - cars, clothes, tools, you name it. He also liked to check out the dumpsters behind stores, like he would find moldy cheese still in the package. He would rinse it with vinegar and eat it, etc.
Once he found a box of 8 1/2 X 11 heavy paper in bright florescent colors, green, yellow, pink and so forth. On one side various words like SALE! or CLEARANCE! or SUPER VALUE! were printed in big black letters at the top so the store could write in the price, etc. with a heavy marker. This paper had never been written on.
A very much loved older sister died and he was asked by the family to give the memorial service. The Hall was packed. Because the reading glasses he got at the second hand store didn't work very well he had to hold his notes up. I felt like crawling under my chair when, you guessed it, he had written his notes on the back of his florescent paper with the above words facing the audience.
