Who Named Him Jack

It's 22° out there.

That's what the WeeGees say.

Definitely a chilly way 

For anyone to start their day.

The winds are calm.

No wind chill warning.

Maybe the nose hairs

Won't freeze this morning.

The humidity 

Is at 85%

Here's to hoping

The fingers don't split.

Last, but not least

The skies are fair.

Now I must hurry.

Time to be elsewhere.

Must warm the car up.
Frost's season is back
No time for Google. 

But, who named him Jack?
