Lucrezia Borgia

Lucrezia Borgia invited a prospective victim to lunch. They ate a hearty meal of roast venison, with a selection of fresh vegetables, all washed down with the finest wine imported from Bordeaux, France.

After the meal, they ate figs and freshly picked grapes.

“Just one apple left”, said Lucrezia, “I insist you have it.

“No”, said the guest, “I couldn’t”.

“Tell you what”, said Lucrezia, “we’ll share it”, and promptly sliced the apple in two with her sharpest knife. The guest and Lucrezia started to eat their respective halves when the guest’s eyes rolled towards the ceiling and he fell over, dead.

“Another victim successfully dispatched,” thought Lucrezia.

How did she do it?

She used a knife coated on just one edge with cyanide. When she sliced the apple in two, only the victim’s half was poisoned.

A Harvest Sown and Reaped

A harvest sown and reaped on the same day
In an unplowed field,
Which increases without growing,
Remains whole though it is eaten
Within and without,
Is useless and yet
The staple of nations.

A war.

Probability That Both Children Are Girls

Walking down the street one day, I met a woman strolling with her daughter. “What a lovely child,” I remarked. “In fact, I have a younger child as well,” she replied.

What is the probability that both of her children are girls?

1/2 probability. This has been know to cause raging debates and is known as one of the variations of the Boy or Girl paradox. This variation is more straightforward because knowing the position of the child leaves only two possibilities – the other child is a boy or a girl, each of which have a 1/2 probability.

Another variation of this can be found here.

I Can Cry Without Eyes

I can cry but I have no eyes.
I can fly but I have no wings.
Wherever I go, darkness follows me.

What am I?

A cloud. Crying is rain, they fly in the sky and darkness follows because they block the sun.

Pitching On The Merry-Go-Round

Everly and I were playing on the merry-go-round at the local park. It was very large and we stood on opposite sides. As we spun the merry-go-round counter-clockwise, I threw a ball to Everly. Did the ball go to Everly, to the right or left of them?

Since the merry-go-round had moved while the ball was traveling to Everly the ball went to the right of them.

With piercing force it doles out fate,
Over bloodless victims proclaiming its might,

Yet flying swiftly past;

For adults I’m gone too fast.
