Because winter is the season in which we hardly ever see the moon

The Moon
You can take the moon by the spoonful
or in capsules every two hours.
It's useful as a hypnotic and sedative
and besides it relieves
those who have had too much philosophy.
A piece of moon in your purse
works better than a rabbit's foot.
Helps you find a lover
or get rich without anyone knowing,
and it staves off doctors and clinics.
You can give it to children like candy
when they've not gone to sleep,
and a few drops of moon in the eyes of the old
helps them to die in peace.

Put a new leaf of moon
under your pillow
and you'll see what you want to.
Always carry a little bottle of air of the moon
to keep you from drowning.
Give the key to the moon
to prisoners and the disappointed.
For those who are sentenced to death
and for those who are sentenced to life
there is no better tonic than the moon
in precise and regular doses.
