We can thank Queen Victoria herself for help here. In a letter to one of her daughters, she wrote that, “Keep up your pecker” means, “Keep up your spirits, and don’t be downhearted” (258). Despite the queen’s implied approval of the expression, American directors may want to effect some discreet substitution. They might try this:
Edwin: Is this the court of family cases? (alarmed) I see no smiles upon their faces!
Or, as suggested by Green (89): “It is, it is the Exchequer.”
