well done kabu,

Thanks everyone, here's one I hope is slightly tougher than my last


I am a destroyer of men!
Count my pieces, it will equal seven.
The first letter seen is my second.
exchange it with number fifteen
and I will be far less deadly
than I could have been.
What am I?

This is a word problem, and there is one very good answer and two possibles.

Sorry, no idea.

Why do you think I'm not taking honors puzzle-solving in school

I robbed this one from a website on riddles, no answer was posted

23. Which of the following statements are true?

1. At least one of these ten statements is false.
2. At least two of these ten statements are false.
3. At least three of these ten statements are false.
4. At least four of these ten statements are false.
5. At least five of these ten statements are false.
6. At least six of these ten statements are false.
7. At least seven of these ten statements are false.
8. At least eight of these ten statements are false.
9. At least nine of these ten statements are false.
10. At least ten of these ten statements are false.

tough one.

at first glance i think it's #1 though. reasoning behind it is that #10 is definitely false since it cannot be true (it would contradict itself); all others may be true or false.
