Two guys, one 80 and one 87...

Two guys, one 80 and one 87, were sitting on their usual park bench one morning.
The 87 year old had just finished his morning jog and wasn't even short of breath.
The 80 year old was amazed at his friend's stamina and asked him what he did to have so much energy.
The 87 year old said, "Well, I eat Italian bread every day. It keeps your energy level high and you'll have great stamina with the ladies."
So, on the way home, 80 year old stops at the bakery. As he was looking around, the lady asked if he needed any help. He said "Do you have any Italian bread?"
She said, "Yes, there's a whole shelf of it. Would you like some?"
He said, "I want 5 loaves."
She said, "My goodness, 5 loaves ... by the time you get to the 5th loaf, it'll be hard."
He replied, "I can't believe it, everybody knows about this sh*t but me."

Typesetting machine patent

In 1841, the first U.S. patent for a typesetting machine was issued to Frenchman Adrien Delcambre and Englishman James Hadden Young, both residing in Lisle, France (No.2,139). Their "Pianotyp" placed letters side by side in their proper places "by means of ... inclined planes upon which the types are thrown and allowed to descend by various channels meeting at one point to what we call the composing box." The machine was operated using "a number of keys similar to those of a pianoforte which act as levers which push the types [which fall] by their own gravity to the said box whenever the keys are depressed." It was patented in England* on 13 Mar 1840, and used in London (1841) to set The Phalanx weekly magazine*.«
