Tymerian Empire
From Tardis Wiki, the free Doctor Who reference
The Tymerian Empire was the empire of the Tymerian race, ruled by her Royal Tectrope. The fall of the empire was a direct result of the outlawing of doors, after her Royal Tectrope got her fourth proboscis jammed in a suction door.
As a result, members of the empire had to use the stairs instead of lifts and windows instead of doors. Productivity dropped and the economy eventually crashed. (NSA: Forever Autumn)
