You know its cold outside when...

1) Its warmer in your freezer.

2) Your hand sticks to the doorknob when you try to open it.

3) You cough when trying to breath the air.

4) Your eyebrows and eyelashes accumulate a visible layer of frost.

5) There’s less than a half-inch of mercury left in your thermometer.

6) The dog won’t go outside.

7) Your toes are perpetually numb.

8) The trees are white with hoar frost.

9) Your car won’t start.

10) Ice accumulates on the inside of your windows.

It’s not cold in Boston.
