Update on open window in winter

The story goes,
"I was in the apartment on Saturday to install a wi-fi for the computer and was cooking some pizza.  The oven started smoking.  I haven't used the oven in quite awhile so I don't know what happened.  Anyway, I opened the window to let the smoke out.

The window is not on the windward side so it shouldn't have been a problem."

Oh OK, minus 4 degrees F. and the open window is over a sink; no chance the pipes could freeze.

Cool.

Speaking of cool; it's currently 27 degrees outside so I'm going out for a 2 mile walk.  No really!
