Uneasy lies the head that wears a crown.
2 Henry IV Act 3 Sc 1
The cares of kingship weigh heavily on Henry IV.
He came to power by seizing the throne from his predecessor Richard II, and now has his murder on his conscience. The powerful nobles that set him on the throne are about to turn against him.
And his heir, Prince Hal, spends his time with a bunch of ne'er-do-wells in the London stews, drinking and thieving. Hal's partner in crime is Shakespeare's greatest comic creation, the fat fantasist Sir John Falstaff, a charmer and con-man with no thought for anyone's good except his own.
If all the year were playing holidays,
To sport would be as tedious as to work.
Prince Henry, 1 Henry IV Act 1 Sc 2
