"A door is what a dog is perpetually on the wrong side of." [Ogden Nash]First record of dooryard is c.1764, Amer.Eng.; doorstep is from 1810.
show someone the door
Order someone to leave, as in I never should have listened to him; I should have shown him the door at once. This expression, first recorded in 1778, is not the same as show someone to the door (see under show someone out).
