I was thinking Park Place or Boardwalk myself, but then I'm in the States.

ok so it's monopoly related
:-)

i stopped playing monopoly... it's a game where you have to humiliate the other player... great if you're winning... not good for relationships
;-) especially with 2 bad losers and 2 evil streaks

Message for all Monopoly players - it's only pretend money. Sorry if that spoils it for you.

There's a travel book on it called 'Do Not Pass Go', and very good it is too, if a little expensive.

ah, the chap that also did the Tour de France for a laugh. Or, more accurately, the same route as le Tour. Good book. 'French Revolutions' it's called.

I'm waiting for 'Do Not Pass Go' to come out in @#$%& paperback...

My little brother was once playing Monopoly with two friends of his who couldn't read. He claimed that the Chance card he'd drawn read "Go directly to Free Parking. If you pass go collect $200". I called him on it, so he threw his yo-yo at me. I might have let it go if he hadn't added the last bit (since I wasn't playing).

Of course, my brother always wanted to banker. We discovered why when we realized that in his version of the rules it was OK for the banker to steal from the bank as long as he didn't get caught.

How about a new one:

A man lives on the 12th floor of a block of flats. Every day he steps out of his flat and into the lift, takes it to the ground floor, and goes to work. When he comes home, he takes the lift to the 9th floor and walks the rest of the way up to his flat on the 12th floor. He hates walking, so why does he do it?

Easy, easy, easy.

As in I heard this one years ago. And it has nothing to do with getting exercise.

Can I add an extra bit to the riddle and also change it a little bit, please?

A bloke, let us call him George for no particular reason other than that was his name, lives on the 30th floor of a tower block. Every day he gets out of bed, pulls on his clothes, brushes his teeth and engages in other acts of trivial importance that serve no other purpose than to extend the question.

After doing all this George sets out to work and takes the lift down to the ground floor.

On sunny days when George comes home he takes the lift to the 15th floor and walks up the remaining 15 flights of stairs. However if it was raining when George left his flat that morning then he takes the lift to the 28th floor before getting out and walking.

George is no fitness addict, and doesn't even like using stairs.

Explain.

PSD: I like it. Could he have got all the way home on the sunny days when he'd been out punting ?

No - as he'd be picked up by the college wassnames well before he got back.

But I know what you mean.

The answer to the nine balls, as Rob seems to have forgotten it and I'm sure I've got the answer (I actually missed my bus stop this morning due to puzzling over it, but twigged the answer as I got off so I guess it was worth it), is two weighings on the balance.

The first weighing should be three balls versus three balls. If one set is lighter than the other then you know the light ball is in that set; if they balance it must be in the remaining three balls.

Then take two of that set of three and weigh them against each other using the same logic - if one ball is lighter it is obviously the lighter one, and if they balance then the light ball is the other one from that set.

Edit -> This should come after PSD's college wassnames thing but he beat me with other posts inbetween.

That's true. They can be pretty vicious. Even when you're taking the punt you've booked, getting the key involves handing over passports, birth certificates signed in triplicate and sir has to promise on sir's life that it will be returned before nightfall.

There was one time when we'd been out punting (got most of the way to Grantchester) and drunk several bottles of wine. As we came back through Trinity they were doing a very sophisticated choral recital with the audience on one bank, the orchestra on the other and the choiresters on a punt/stage floating on the river. Very posh, very Cambridge - they had boaters and everything.

Until some drunken reprobates collided with them...

Really quite embarrassing but we had to get home and punting in a straight line isn't easy at the best of times.

PSD: You're correct. Magda gave the answer and there were no requests for an explanation so I didn't bother.

Zeno's paradox is that an infinite sum can sum to a finite value.
For example, 1/2 + 1/4 + 1/8 + 1/16 + ... = 1

I can do a more detailled explanation if really required...

Rob, email edited... but Dave sent me the answer already and i knew it but just couldn't remember, if i'd seen the add on with the umbrella i'd remember it...

Yeah, I'm afraid I'd forgotten the umbrella bit. Mea culpa.

Anyone heard how Aristophanes measured the circumference of the earth in 200 BC or thereabouts? No? Okay, so how did he do it, using the fact that:

A: Aristophanes didn't have access to modern technology.

B: He never moved from the ancient world as then was.

Seems impossible? It isn't. He was quite accurate, too!

I know this one. (Which is more than I can say for the others). However <pedant> it was one Eratosthenes who did it ... Aristophanes was a Greek playwright, while Eratosthenes was the second librarian of the Great Library of Alexandria. </pedant>

I might add that Eratosthenes' accuracy is questionable; he gave the answer of 250,000 stadia (a stadium being a Greek measure). Problem; we don't know how long a stadium actually was. There is a nasty suspicion that the answer usually given was obtained by assuming Eratosthenes was right, and dividing accordingly.

And didn't argument about Eratothingys results lead Chris Columbus to believe that the earth was smaller than it is & thus Cuba was just off the coast of Japan?
