Richard and the Bikini-clad Sisters
RAY: The inspiration for this puzzler came in 2001 from a fellow named Richard Jacobs. Here it is:
Back in the mid 90's, when I was a young medical student, I had the good fortune of spending a couple of days off on the beach in beautiful Boca Raton, Florida. While there, I met two gorgeous, nearly identical blondes, in bikinis no less and they were actually talking to me! I had to pinch myself!
Before I ran out of things to say, I felt compelled to mention to them that I had never seen a cuter set of twins in my entire life.
'Oh, we're not twins,' one of them said. 'In fact, one of us is six years older than the other.'
The other one said, 'While we look identical there is a way to tell which one of us is the older sister, and if you guess right, we'll take you out to dinner and a night on the town.'
'Whoopee!' I exclaimed. 'C-c-c-c-c-can I ask a question?'
'Sure,' they said.
And the question was this: 'Has either one of you ever left the country for any reason?'
Both of them answered, 'No,' but at that instant, both of them knew I had won my free dinner. How did I know which sister was older?
Think you know? Drop Ray a note!
