Puzzles and Riddles

From time to time, logical riddles grab me and keep me fascinated for some time. Over the years, I've come across some really great ones, so, for as long as the fascination holds, I'll try to give you some.

I prefer the type of logical puzzle that doesn't require a piece of paper and/or a higher knowledge of mathematics to solve. My first example is a good one.

Why are manhole covers round (rather than square)?

There's a very simple and logical answer to that question. Try and guess it before you read the rest of the entry. It might take some thought.

I was expecting you to read this too soon, so I rot13'd the answer for you to keep you guessing a little longer:

Znaubyr pbiref ner ebhaq fb gurl pna'g snyy vagb gur ubyr gung gurl pbire. N fdhner znaubyr pbire pbhyq snyy vagb gur ubyr naq frevbhfyl vawher gur crefba va gur frjre, fvapr gur qvntbany bs gur ubyr vf ybatre guna gur fvqrf bs gur pbire.

See? Once you see the solution, it makes a lot of sense.
