It was three o'clock in the morning, and the receptionist at a posh hotel was just dozing off, when a little old lady came running towards her, screaming.
"Please come quickly!" she yelled, "I just saw a naked man outside my window!!!"
The receptionist immediately rushed up to the old lady's room.
"Where is he?" asked the receptionist.
"He's over there," replied the little old lady, pointing to an apartment building opposite the hotel.
The receptionist looked over and could see a man with no shirt on, moving around his apartment. "It's probably a man who's getting ready to go to bed," she said reassuringly. "And how do you know he's naked, you can only see him from the waist up?"
"The dresser, honey!" screamed the old lady. "Try standing on the dresser!"

### Black American patent

In 1954, a patent for "Methods and Means of Defrosting a Cold Diffuser" was issued to its Black American inventor, F.M. Jones (No. 2,666,298). It gave a method to defrost using a heating medium when the surface of the diffuser has accumulated a layer of frost or ice which would otherwise reduce its heat transfer capacity. He used a compressor, condenser and evaporator which were interconnected in a manner such that the compressed refrigerant could also accomplish the defrosting of the evaporator in a defrosting cycle. He was a prolific inventor, whose first patent was for a "Ticket Dispensing Machine" in 1939 (No. 2,163,754), accumulating about 20 more patents relating to gas engines and refrigeration devices in 20 years.
