The Fragile Bridge

You have to cross a long bridge which supports weight up to 180 pounds. However, you weigh 175 pounds and also carry with yourself 3 golden eggs, each of which weighs 2 pounds. How can you get to the other side?

 P. S. If you leave an egg unattended, someone can steal it.

Simply juggle the eggs while crossing the bridge.

$5 Bill

Bern tells Sandy, “This isn’t the $20 bill you left on the table. It is mine – I was keeping it between pages 15 and 16 of my textbook.”
Sandy retorts, “You are lying and I can prove it.” How does she know?

Pages 15 and 16 are on the same sheet of paper in the textbook (just like pages 1 and 2 are) and therefore the bill couldn’t be between them.
