Is Boris Trying To Emulate Prince Hal?

I know you all, and will awhile uphold
The unyoked humour of your idleness.
Yet herein will I imitate the sun,
Who doth permit the base contagious clouds
To smother up his beauty from the world,
That when he please again to be himself,
Being wanted, he may be more wondered at
By breaking through the foul and ugly mists
Of vapours that did seem to strangle him.
If all the year were playing holidays,
To sport would be as tedious as to work;
But when they seldom come, they wished-for come,
And nothing pleaseth but rare accidents.
So, when this loose behaviour I throw off
And pay the debt I never promisèd,
By how much better than my word I am,
By so much shall I falsify men’s hopes;
And like bright metal on a sullen ground,
My reformation, glitt’ring o’er my fault,
Shall show more goodly and attract more eyes
Than that which hath no foil to set it off.
I’ll so offend to make offence a skill,
Redeeming time when men think least I will.
