Do Something Nice

Unable to attend the funeral after his Uncle Charlie died, a man who lived far away called his Blonde brother and told him, 'Do something nice for Uncle Charlie and send me the bill.'
Later, he got a bill for $200.00, which he paid. The next month, he got another bill for $200.00, which he also paid, figuring it was some incidental expense.
But when the $200.00 bills kept arriving every month, he finally called his brother again to find out what was going on.
'Well,' said the Blonde brother, 'you said to do something nice for Uncle Charlie.
So I rented him a tuxedo.'

Paper folding machine

In 1856, the first practical U.S. folding machine to fold book and newspaper sheets was patented by Cyrus Chambers, Jr. of Pennsylvania (No. 15,842). It made three right angle folds to produce a sixteen page folded signature. The machine was installed in the Bible printing house of Jasper Harding & Son, Philadelphia, Pa. Although the accuracy of early folders was poor, with hand folding still predominating for better grade work, development of the folding machine after 1862 was rapid, and in 1873 a machine was patented that would fold a 16-page section and one of 8 pages, inset the latter, and paste it in place. That same year devices to cut and slit paper as it went through the machine were introduced.
