Approval of the Family
When my wife and I decided to get married we'd been going out for a few years. We really loved each other and we wanted everything to be perfect... and pretty much everything was, except that one thing had been bothering me. Her sister was a babe and many times I visited, she would flirt with me, bending over in front of me, things I didn't want to acknowledge.
Well a couple of nights before the wedding, she called me over to help her with some boxes. She was moving out of her apartment. When I arrived, I found her alone on the couch wearing decidedly little. I was shocked and she explained to me that she'd always wanted me and that it was her final opportunity, as these were my last few days as a bachelor. Well, I didn't know what to do. She told me she would go upstairs and wait and if I wanted to, I could follow her, but if I didn't, I could just leave.
I waited for a moment and then went outside only to find her dad almost in tears with joy saying he knew now that I was really the right man and that I had his blessing to marry his daughter. This was a test to see just how loyal I was!
Moral of the story: always leave your condoms in the car.

Thomas DrummondDied 15 Apr 1840 at age 42 (born 10 Oct 1797).Scottish civil engineer who invented the Drummond light (similar to limelight illumination in theatres). As a Royal Engineer he worked on the ordnance survey and attended chemistry lectures by Faraday at the Royal Institution. In the autumn of 1825, while mapping Ireland, Drummond applied limelight to enable surveying by night as well as day and designed an improved Heliostat. To produce a bright light, using an oxygenated alcohol flame, he heated a small ball of lime to incandescent in front of a reflector. From 1828, he attempted to adapt the Drummond light for use in lighthouses, but it was expensive to operate, and by 1831, he instead turned to politics, and by 1835 was Under Secretary of Ireland. His early death was caused by overwork.« |
