Stammering, (says Coleridge,) is sometimes the cause of a pun. Some one
was mentioning in Lamb’s presence the cold-heartedness of the Duke of
Cumberland, in restraining the duchess from rushing up to the embrace of
her son, whom she had not seen for a considerable time, and insisting on
her receiving him in state. “How horribly _cold_ it was,” said the
narrator. “Yes,” said Lamb, in his stuttering way; “but you know he is
the Duke of _Cu-cum-ber-land_.”
