One Monday morning a mailman is walking the neighborhood on his usual route. As he approaches one of the homes he noticed that both cars were in the driveway. His wonder was cut short by Bob, the homeowner, coming out with a load of empty beer and liquor bottles. "Wow Bob, looks like you guys had one hell of a party last night." the mailman comments.
Bob in obvious pain replies, "Actually we had it Saturday night. This is the first I have felt like moving since 4:00 am Sunday morning. We had about fifteen couples from around the neighborhood over for Christmas Cheer and it got a bit wild. Hell, we got so drunk around midnight that we started playing WHO AM I."
The mailman thinks a moment and says, "How do you play that?"
Well all the guys go in the bedroom and we come out one at a time with a sheet covering us and only our "privates" showing through a hole in the sheet. Then the women try to guess who it is."
The mailman laughs and says, "Damn, I'm sorry I missed that."
Probably a good thing you did," Bob responds. "Your name came up four or five times."

Carl Auer, Freiherr von WelsbachBorn 1 Sep 1858; died 4 Aug 1929 at age 70.Carl Auer Freiherr (baron) von Welsbach was an Austrian chemist, physicist and engineer whose invention of the gas mantle greatly improved the brightness of light that could be obtained from gas lamps. While doing flame tests to examine the spectrum of certain rare earth compounds, he observed the small beads of test material on a platinum wire became white-hot and incandescent. He then had the idea to soak cotton webbing with a solution of the salts, then burn out the cotton leaving a matrix of the compound. His experiments began with slightly promising results with lanthanum oxide, then a mixture with magnesia. He also tried zirconium oxides and others before adding thorium oxide which made commercially viable mantles. His invention was adopted around the world wherever manufactured gas was available, meaning he had a profitable business improving and manufacturing them.« |
