Yorick

Yorick,
in Shakespeare's Hamlet (v. i), the king's jester, whose skull the grave-diggers throw up when digging Ophelia's grave;
in Sterne's Tristram Shandy , ‘the lively, witty, sensible, and heedless parson’, of Danish extraction, and probably a descendant of Hamlet's Yorick. Sterne adopted ‘Yorick’ as a pseudonym in his Sentimental Journey and entitled his own homilies The Sermons of Mr Yorick, first published in 1760 .
