Sewing machineIn 1842, the first U.S. patent (of which there is any record) for a sewing machine was issued to John J. Greenough of Washington, DC. (No. 2,466) as "A Machine for Sewing or Stitching all Kinds of Straight Seams." The needle was gradually tapered to a point at each end, with an eye in the middle. It used pairs of pinchers, one on each side of the work to alternately draw the thread back and forth. It did not use thread from a bobbin of thread. Instead, the lengths of thread were inserted in the needle, similar in length to those used in hand sewing.*
A little boy was doing his math homework. He said to himself,
"Two plus five, that son of a bitch is seven. Three plus six, that son of a bitch is nine...."
His mother heard what he was saying and gasped, "What are you doing?"
The little boy answered, "I'm doing my math homework, Mum."
"And this is how your teacher taught you to do it?" the mother asked
"Yes," he answered.
Infuriated, the mother asked the teacher the next day, "What are you teaching my son in math?"
The teacher replied, "Right now, we are learning addition."
The mother asked, "And are you teaching them to say two plus two, that son of a bitch is four?"
After the teacher stopped laughing, she answered, "What I taught them was, two plus two, THE SUM OF WHICH, is four."
