I have a clock(12-hour format) and both the needles of the clock overlap at 12:00.

Riddle me this, Riddle me that,
What am I? I am made of wood, but you can't see me down?

I am under you when I am whole.
I shift above you if you remove the first letter.
I come all around you if you remove the second as well.

I look flat, but I am deep. Hidden realms I shelter. Lives I take, but the food I offer. At times I am beautiful. I can be calm, angry, and turbulent. I have no heart but offer pleasure as well as death. No man can own me, yet I encompass what all men must have. What am I?

A man started to town with a fox, a goose, and a sack of corn. He came to a stream which he had to cross in a tiny boat. He could only take one across at a time. He could not leave the fox alone with the goose or the goose alone with the corn. How did he get them all safely over the stream?

You knock a Table over in the library, and suddenly 20 eyes are looking at you.

I don't get anymore wetter, no matter how much rain falls on me.
