You're on a ski lift, going from the bottom of the mountain to the top. How many chairs from the other side will you pass by?
A few choices:
1. Half of them
2. 2/3 of them
3. All of them (but yours)
4. 3/4 of them
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
The answer is C - all of them but yours.
The chairs are in a giant loop, with several stopping places on the way to the top, and you will see all the chairs probably more than once before you get up there.
This was Gollum's final riddle from The Hobbit:
"This thing all things devours;
Bird, beasts, trees, flowers;
Gnaws iron, bites steel;
Grinds hard stones to meal;
Slay king, ruins town,
and beats a mountain down."
