Toilet Seat

A man decides to take the opportunity while his wife is away to paint the wooden toilet seat.
The wife comes home sooner than expected, sits, and gets the seat stuck to her rear. She is understandably distraught about this and asks her husband to drive her to the doctor.
She puts on a large overcoat so as to cover the stuck seat, and they go.
When they get to the doctor's, the man lifts his wife's coat to show their predicament. The man asks, "Doctor, have you ever seen anything like this before?"
"Well, yes," the doctor replies, "but never framed."

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.]
