Condoms
One day on the way home from work, I stopped at the local Pharmacy and while I was checking out, I picked up some candy to take home for me and my 7-year old son. It was a bag of Gold Coins (Gold Foil- covered chocolate candy coins).
There were many sizes, from dime to dollar. I took the bag home, and me and my son opened the bag and ate all of the coins, my son taking the bigger dollar-sized ones and me taking the smaller ones.
The next day, my wife, my son and I stopped at the Pharmacy again to pick up a few things. While my wife and I were shopping, we noticed that my son had picked up a Gold Coin Condom. Before we could catch him, he took it up to the counter and asked the Pharmacist, "What's this?"
The woman, looking very serious, said, "That's a condom, son."
To which my son replied, "My daddy BOUGHT me some of these yesterday!"
With a disgusted look on her face, the Pharmacist replied, "Those are NOT for children, young man."
And finally, my son replied, "Then I'll buy this one for my Daddy. He likes the LITTLE ones!"

Solar flareIn 1859, a solar flare was observed for the first time by astronomer Richard C. Carrington. He reported his Description of a Singular Appearance seen in the Sun in the Monthly Notices of the Royal Astronomical Society (1860), "While engaged in the ... observation of ... solar spots ... two patches of intensely bright and white light broke out. ... I therefore noted down the time, ... and seeing the outburst to be very rapidly on the increase ... I hastily ran to call some one to witness ... and on returning within 60 seconds, was mortified to find that it was already much changed and enfeebled. Very shortly afterwards the last trace was gone. In this lapse of 5 minutes, the two patches of light traversed a space of about 35,000 miles." |
