No degrees

There's no more 'F's in this here thermometer.
Zeeero.

Actually, it's -0.5F.

Try this experiment:
Pour a glass of water.
Place it in the refridgerator for 1/2 hour.
Take the glass outside into the middle of a large hard surface, such as a parking lot.
Throw the water straight up into the air as hard as you can.
By the time it reaches the ground you will be an ice cold idiot.

Repeat.
