Some characters are in a room. They are trying to accomplish something; solving a puzzle, wait for something to arrive or happen, or perhaps get Homer to answer to "Mr. Thompson"
. To show how long they've been at this, the scene will cut ahead, and they will have taken off any coat they might have been wearing, rolled up their sleeves, or removed their ties.
Used to show an absurdly long yet absurdly dull task's accomplishment, or used more spaciously over the course of a more serious work to show the characters are getting weary; to cool off and weigh less, they have removed their coats and ties to show they are tired and don't care about looking dissheveled anymore.
