Gone Camping
Four friends spend weeks planning the perfect lake camping and riding trip.
Two days before the group is to leave Rob's wife puts her foot down and tells him he isn't going.
Rob's friends are very upset that he can't go, but what can they do.
Two days later the three get to the camping site only to find Rob sitting there with a tent set up, firewood gathered, and supper cooking on the fire.
"Dang man, how long you been here and how did you talk your wife into letting you go?"
"Well, I've been here since yesterday. Yesterday evening I was sitting in my chair and my wife came up behind me and put her hands over my eyes and said 'guess who'?"
I pulled her hands off and she was wearing a brand new see through nightie. She took my hand and took me to our bedroom. The room had two dozen candles and rose pedals all over. She had on the bed, handcuffs and ropes! She told me to tie and cuff her to the bed and I did. And then she said, "now, you can do what ever you want."
So here I am.
Find number abc
If c04a9 - aa159 = 5cab0 find number abc. Multiple solutions may exist. Peter Cooper HewittBorn 5 May 1861; died 25 Aug 1921 at age 60. American electrical engineer who invented the mercury-vapour lamp, an important forerunner of fluorescent lamps. He studied the production of light using electrical discharges (while Thomas Edison was still developing incandescent filaments). The mercury-filled tubes he developed from the late 1890s, gave off an unattractive blue-green light. Although unsuitable in homes, its brilliance won wide adoption by photo studios because the black and white film of the time needed just bright light, despite its colour. There were many other industrial uses for the lamp. His manufacturing company (est. 1902) was bought by General Electric in 1919 which produced a new design in 1933. He took out his first eight mercury vapour lamp patents on 17 Sep 1901.« |
