Abe and Esther are flying to ...
Abe and Esther are flying to Australia for a two-week vacation to celebrate their 40th anniversary. Suddenly, over the public address system the Captain announced, "Ladies and Gentlemen, I am afraid I have some very bad news. Our engines have ceased functioning and we will attempt an emergency landing. Luckily, I see an uncharted island below us and we should be able to land on the beach. However, the odds are that we may never be rescued and will have to live on the island for the rest of our lives!"
Thanks to the skill of the flight crew, the plane lands safely on the island. An hour later Abe turns to his wife and asks, "Esther, did we pay our $5,000 PBS pledge check yet?"
"No, sweetheart," she responds.
Abe, still shaken from the crash landing, then asks, "Esther, did we pay our American Express card yet?"
"Oh, no! I'm sorry. I forgot to send the check," she says.
"One last thing, Esther. Did you remember to send checks for the Visa and MasterCard this month?" he asks.
"Oh, forgive me, Abie," begged Esther, "I didn't send that one, either."
Abe grabs her and gives her the biggest kiss in 40 years.
Esther pulls away and asks, "What was that for?"
Abe answers, "They'll find us!"

Sir William PerkinDied 14 Jul 1907 at age 69 (born 12 Mar 1838). Sir William Henry Perkin was an English chemist and inventor who, in his youth, was enthused about chemistry by attending public lectures by Michael Faraday. While experimenting to synthesize quinine from a coal tar chemical, Perkins mixed aniline and sodium dichromate and unexpectedly found a dense colour - he named as aniline purple - which he extracted with alcohol. He had discovered the first artificial dye. Textiles of his era were coloured from natural sources; his was a valuable alternative. At the age of 18, he patented the dye. His father invested in his efforts to manufacture the dye. It went on sale in 1857, and it became popular in France. By age 23 he was fathering a new synthetic organic chemical industry. He continued synthesis research. He was knighted in 1906. |
