There's a Bill Bailey joke on the theme.
An infinite number of mathematicians walks into a pub. The first mathematician walks up to the bar and asks for one pint of beer, the second goes up and says "I'll have half of what he's having." The third walks up before the bartender interrupts, "Hold on, I'm not having any of that," he says, before pouring two pints.
Alexander is 20 years old in 1980, but only 15 years old in 1985. How is this possible?
The solution in B.C. era is sound mathematically, but not historically. 2000 B.C. when "our" Alexander was born, the name wasn't known.
Pelikan there is a simpler answer to your riddle: ask each man if he is a human! One of them will lie.
And you've wasted your one question and not found out how to get to town.
Alternatively, you could say to either man "Were I to ask you if this road leads to town, would you tell me that it does?" The truth-teller will tell you the truth about the true answer he would give you, and the liar will lie about the lie he would tell you, and in both cases it comes back to the truth.
Now a little rhyme: "A voiceless folk with a famous sound, and a royal ruler who never was crowned; Their treasury stored with a golden hoard Not cast into ingots nor coined in the round".
You
"In theory, theory and practice are the same; in practice they are not." I don't know who said that, but I've lived long enough to know how true it is. At least in theory.
What is the latest question?
There is a flea in the middle of a circle. The radius of the circle is 10 meters. The flea can jump 5 meters, but after that it will be tired and can only jump 2.5m on its next jump. Each time it jumps the distance it can travel halves. How many jumps will it take for the flea to leave the circle? (assume that the flea occupies no space or that all the distances are measured from it's exact centre.)
2, assuming sufficient rest between the jumps.
he has a really bad calander
A hole?
Good answer.......
Now a little rhyme: "A voiceless folk with a famous sound, and a royal ruler who never was crowned; Their treasury stored with a golden hoard Not cast into ingots nor coined in the round".
This one is driving me crazy!

A beehive!
I was thinking ant colony for ages.
Look at this riddle.
Mr. and Mrs. Schlobodkins conducted a party inviting four couples.The people who attended the party gave handshakes to each other.But not everyone shaked hands with all.No one shaked hands with their spouse and none shook hands with another twice.
In the end,Mr.Schlobodkins asked everyone,including Mrs.Schlobodkins,how many handshakes they gave.Each gave different answers.Then,how many hands did Mrs.Schlobodkins shake?
Now a little rhyme: "A voiceless folk with a famous sound, and a royal ruler who never was crowned; Their treasury stored with a golden hoard Not cast into ingots nor coined in the round".

A beehive!
Good enough. "Bees". 
The fact that someone can walk 100 feet (in above example) seems to break the concept of infinity since there should be an infinite number of measurements he has to pass to reach 100 feet
And there are - indeed, there is an infinite number of rational numbers between 0 and 1, and an infinitely bigger number of irrationals. But what wasn't yet known in Zeno's time, but is now, is that a series with infinite terms can still sum to a finite number. (What I like is that 1/2 + 1/3 + 1/4 + 1/5... goes to infinity, but it gets there ridiculously slowly!)
All couples, being married or not, will give the same number of handshakes. The answer is in the situation where there is an unequal number of handshakes. That is only happening when the next criteria are met:
1. there is an uneven number of visitors,
2. there is no other couple, because all couples will have shake an equal number of hands.
Hence, out of 8 people invited is only 1 person coming. That person shaked two hands and Mrs. Schlobodkins shaked, just as Mr. Schlobodkins exactly 1 hand.
Two detectives walk into a empty room with no windows and find a dead man hanging from the ceiling and a puddle of water below him. The detectives inspect the body and confirm that it was suicide by hanging. How did he manage to kill himself then?
Um... he hung himself?

Everybody came to the party.i.e,10 people,including Mr. and Mrs.Schlobodkins.

He stood on an ice cube and tied the rope around his neck.The ice melted and he died.
The flea will never be able to leave the circle if it can jump only half as far on subsequent jumps.
It's like saying a person wants to walk 100 feet. How can he get there when there is an infinite amount of measurements he has to cross (99.9 feet, 99.99999 feet, 99.9999999999999999 feet and so on.)
That's right, it's based on Zeno's dichotomy paradox.
