 Defenestration 

It was previously reported here (and elsewhere online) that every episode of the show featured ""defenestration of some kind or other"", which isn't true.  Episodes often feature characters jumping out of windows under varying degrees of duress, but for example, in the episode ""They Eat Horses, Don't They?"" the nearest anyone comes is Fraser leaning out of a window to talk to someone on the street."
