Two guys are out hiking. All of a sudden, a bear starts chasing them.
They climb a tree, but the bear starts climbing up the tree after them. The first guy gets his sneakers out of his knapsack and starts putting them on.
The second guy says, "What are you doing?"
He says, "I figure when the bear gets close to us, we'll jump down and make a run for it."
The second guy says, "Are you crazy? You can't outrun a bear."
The first guy says, "I don't have to outrun the bear. I only have to outrun you."

Ice cream freezer

In 1843, a U.S. patent was issued, antedated to 29 Jul 1843, for a hand-cranked ice-cream freezer invented by Nancy M. Johnson (No. 3,254). In previous designs, the ice-cream mixture was held in an inner container, which vessel was itself was rotated within an outer container of ice and salt. Her invention was to add a vertical shaft with curved, perforated paddles within the inner vessel, and reaching nearly to its inside wall. Stirring in one direction would carry the the liquid or semi-fluid mass from the centre to the circumference. Turning in the opposite direction would scrape frozen material and carry it from the inner walls to the centre of the freezer. Thus fresh matter continuously reached the freezing surface.«[Image: detail from patent diagram showing inner container and its paddle.]
