An old man who loves to fish...

An old man who loves to fish, was sitting in his boat the other day when he heard a voice say, "Pick me up."
He looked around and couldn't see any one. He thought he was dreaming when he heard the voice say again, "Pick me up."
He looked in the water and there, floating on the top, was a frog.
The man said, "Are you talking to me?"
The frog said, "Yes, I'm talking to you. Pick me up. Then, kiss me and I'll turn into the most beautiful woman you have ever seen. I'll then give you more sexual pleasure that you ever could have dreamed of."
The man looked at the frog for a short time, reached over, picked it up carefully, and placed it in his front breast pocket.
Then the frog said, "What, are you nuts? Didn't you hear what I said? I said kiss me and I will give you sexual pleasures like you have never had."
He opened his pocket, looked at the frog and said, "Nah, at my age I'd rather have a talking frog."

Valdemar Poulsen

Born 23 Nov 1869; died 23 Jul 1942 at age 72.Danish engineer who in 1903 developed the first device for generating continuous radio waves, thus aiding the development of radio broadcasting. His arc transmitter increased the frequency range of Duddell's Singing Arc (1900) from the audio range to radio waves, enabling speech to be transmitted up to a radius of 150 miles. By 1920 the Poulsen Arc transmitter was as powerful as 1000kW with ranges of up to 2,500 miles. An earlier invention was the Telegraphone, for which he filed a patent in Denmark on 1 Dec 1898. This was the first device in history to use magnetic sound recording, although this invention remained commercially impractical due to low sound output until the advent of vacuum tube amplifiers in the 1930s.[Biog. Dict. of the Hist. of Tech. gives date of death 23 Jul 1942. DSB and EB give Jul 1942.]
