### Round Robin Puzzle

I could be wrong, but I don't think I've ever had a round robin tournament here before, so:

A set of soccer matches is to be organized in a "round-robin" fashion, i.e., every participating team plays a match against every other team once and only once.

If 66 matches are totally played, how many teams participated?

### Slowest Train in the World

A train moves at less than one mph and yet passes dozens of people in less than two minutes. The person in charge who stops the train is not on it. When it stops, it picks up no passengers, which is odd since no one is on it in the first place. When the train returns in the direction it came from, it goes much faster.

Explain.

### 'S' is for Single

What word becomes plural when you add an 'S', but becomes singular when another 'S' is tacked on?

BTW, for those of you who are wondering why I have been remiss in answering the questions the next day, I am being blocked out at my workplace (very unfortunate). But, hopefully I answer each question eventually (from home). I will try to find some more consistent manner of answering, but I have not been able to as yet. (Anyone want to partner with me on this? The pay is lousy, but it can be a lot of fun.)

### You Lost Your Watch?

So here you are, in a strange place and you've lost your watch. You stop a stranger to ask what time it is and he turns out to be even stranger than the place. His answer goes like this:

"The big hand and the little hand are midway between 1 and 2, lying on top of each other."

So, now you need to figure out what time it is.

"The big hand and the little hand are midway between 1 and 2, lying on top of each other."
