Got a riddle similar to this week's High School POTW;
not sure where to post it, so I'll post it here:
John was born in 1987, and is now (2012) 12 years old.

How can that be?

Hmmmm....My mother married my brother, who is my Dad. Even I don't have that problem.

Dan, there is a perfectly valid answer to that riddle...

And your brother being your dad...a little comedy of mine:

I was slowly getting older and confused. So confused that I gave up
when my son was born. I'll tell you about it. Won't take long: the
next four short paragraphs. But get ready: quite a few "steps" involved.
FOR OPENERS.
I meet a widow, who lives with her step-daughter. I marry her. At the
wedding, my father meets the step-daughter, falls in love, and marries
her. So now my wife is my father's mother-in-law, and my wife's step-
daughter is my step-mother. Plus I am the step-father of my step-mother.
YOU AIN'T SEEN NOTHING YET.
My step-mother and father lose no time and a boy is born. Now this guy
is my step-brother. And as this guy is the son of my wife's step-daughter,
this makes my wife this guy's grandmother. Also makes me the grandfather
of my step-brother.
IT ONLY GETS WORSE.
You guessed it. Now my wife gives birth to a baby boy. My step-mother is
now my son's step-sister and also my son's grandmother since he is the son
of her step-son. And my father is now the brother-in-law of his grandson..
or is it the step-brother-in-law?
NOW FOR THE CLINCHER.
All this clearly shows that my wife is my father's mother-in-law plus that
I am the grandfather of my step-brother. Get the picture? Therefore, I am
my father's something-or-other-father-in-something-or-other which makes me
my own grandfather. Which is why I'm taking me to McDonald's. I guess I'll
be able to give myself grandfatherly advice over a Big Mac, Medium Fries
and a Large Diet Coke.

NOTES.
1- I mailed a firm of experts in family reconstructions a request for a
family-tree, along with a cheque representing their fee; the cheque was
returned to me.
2- Afraid that some other boy might be born and in all probability make
me my own great-grandfather, I asked my father's mother-in-law for a
divorce; she agreed quickly as she was aging as quickly as I was.
3- My father, who was getting younger and younger due to these births,
quickly found a new husband for my former wife: my older brother.
4- Update: yes, a boy was born out of this new union and who knows: I'm
now probably my own great-grand-uncle!

Guess it's time for the answer:
1987 = hospital room number !

If the difference in "year" numbers had been 4 times the age, or 4 times the number of birthdays, I'd have suspected some Feb. 29 foolery going on.

OK, along the same lines (and true - for small values of true), my brother (or rather one of my brothers) was born in March but has his birthday in January (in the same year though).

The semantics of the above riddle are not precise enough to formulate a meaningful answer.
