Today's Quiz

This one is not a joke.

Which word has three double letters in a row?
bookkeeper (or bookkeeping)

This one is a favorite of my sister.

In Russia before the revolution everyone was penniless, except the Tsar.  Why is that?
He was Nicholas.

Finally, here we will prove a theorem.  The theorem is that all horses have an infinite number of legs.  To prove this theorem we will take as a lemma that all horses are of the same color.  A lemma is a smaller result used to prove a larger result.

Proof:  Take your average horse.  It has two hind legs and forelegs.  Together that makes six legs.  Six is an even number, but it is an odd number of legs for a horse.  The only other number that is both even and odd is infinity, so a horse has an infinite number of legs. 

You may say that you can find a horse that doesn't have an infinite number of legs.  But by the lemma -
that must be a horse of a different color!
