<p>You whiz around the corner in your rented moped when suddenly you're forced to come to a sudden stop.</p>
<p>It seems a funeral procession has stopped for a quick breather. Empathy overwhelms you and you offer your condolences to the whimpering man nearby. "Were you close?" you ask, wishing you hadn't. </p>
<p>After a moment, the man replies, "Brothers and sisters I have none, that man's father is my father's son." </p>
<p>That sounds sarcastic, you think to yourself. Maybe the guy doesn't want to tell you, which is fine, but there's no reason to be a smartass about it. </p>
<p>Or, perhaps the clever among can see this is the real answer.</p>

<p>Well, now that I think about it, it's a paradox. If he was lying, then he would be saying that he is truthful, which he wouldn't be because he's lying. Just say no to paradoxical riddles!</p>
<p>You approach two talking doors. One door leads to the City of Truth, while the other door leads to the City of Liars. You do not know which door is which. You are able to ask only one question to determine which door is which. The door that leads to the City of Liars always speaks lies, while the door that leads to the City of Truth always speaks the truth. You want to go to the City of Truth. What question do you ask to determine which door leads to the City of Truth?</p>
<p>As I was walking to St. Ives,
I met a man with seven wives.
Each wife had seven sacks,
Each sack had seven cats,
Each cat had seven kits.
Kits, cats, sacks and wives--
How many were going to St. Ives?</p>
