A very shy guy goes into a bar...

A very shy guy goes into a bar and sees a beautiful woman sitting at thebar. After an hour of gathering up his courage he finally goes over to herand asks, tentatively, "Um, would you mind if I chatted with you for awhile?"
She responds by yelling, at the top of her lungs, "No, I won't sleep withyou tonight!" Everyone in the bar is now staring at them.
Naturally, the guy is hopelessly and completely embarrassed and he slinksback to his table.
After a few minutes, the woman walks over to him and apologizes. Shesmiles at him and says, "I'm sorry if I embarrassed you. You see, I'm agraduate student in psychology and I'm studying how people respond toembarrassing situations."
To which he responds, at the top of his lungs, "What do you mean $200?"

Carbon paper

In 1806, Englishman Ralph Wedgwood secured the first patent for carbon paper, which he described as an “apparatus for producing duplicates of writings.” In his process, thin paper was saturated with printer's ink, then dried between sheets of blotting paper. His idea for the carbon paper was a byproduct of his inventionof a machine to help blind people write, and the “black paper” was really just a substitute for ink. In its original form, Wedgwood's “Stylographic Writer” employed a metal stylus instead of a quill for writing, with the carbon paper placed between two sheets of paper in order to transfer a copy onto the bottom sheet.
