Devil finds work for idle hands
Different ropes for different folks
Different strokes for different folks
Discretion is the better part of valour
Does a one-legged duck swim in circles?
Don’t bite the hand that feeds
Don’t catch your chickens before they’re hatched
Don’t judge a book by the cover
Don’t know whether to wind a watch or bark at the moon
Don’t look a gift horse in the mouth
Don’t stand there with curlers in your hair
Don’t stop and kick at every dog that barks at you
Don’t throw bricks when you live in a glass house
Don’t trouble trouble until trouble troubles you
Don’t wash your dirty laundry in public
Dot all the i’s and cross all the t’s
Down in the doldrums
Drunker than a peach orchard boar
