# Talk:2403: Wrapping Paper

Merry Christmas -- bubblegum (talk) *(please sign your comments with ~~~~)*

I was reminded of the old http://bjornsmaths.blogspot.com/2005/11/how-to-catch-lion-in-sahara-desert.html

The method of inverse geometry: We place a spherical cage in the desert and enter it. We then perform an inverse operation with respect to the cage. The lion is then inside the cage and we are outside.

- An engineer, a physicist, and a mathematician are shown a pasture with a herd of sheep, and told to put them inside the smallest possible amount of fence.
- The engineer is first. He herds the sheep into a circle and then puts the fence around them, declaring, "A circle will use the least fence for a given area, so this is the best solution."
- The physicist is next. He creates a circular fence of infinite radius around the sheep, and then draws the fence tight around the herd, declaring, "This will give the smallest circular fence around the herd."
- The mathematician is last. After giving the problem a little thought, he puts a small fence around himself and then declares, "I define myself to be on the outside."

Sorry but this immediately brings Jevil (Deltarune) to mind. 108.162.216.198 09:17, 27 December 2020 (UTC)

Maybe we could make Klein bottle-shaped wrapping paper, it can: (1) let everything in the universe be the gift, including what is inside (well, I know it's unreasonable to say something is “inside” a Klein bottle) the gift box; (2) reduce the cost of printing to zero.

## My hobby[edit]

Prank Randall by selling him wrapping paper that is printed on both sides so he can't turn it inside out 172.69.33.220 02:46, 26 December 2020 (UTC)
