I am glad to see Shakespeare up if only for the fact that there's a lot of him to meander through!
My favourite play is a tie between A Midsummer Night's Dream and 12th Night, with Romeo and Juliet in close second - although I find the latter two slightly more quotable. Perhaps long sentences are not the best for prompts meant for a thousand words at most, but I'll offer some up in any case.
I tried to put this behind a cut to be polite. I really tried. But it wouldn't go, so I'm afraid... it's all out here. I'm deeply sorry.

HIPPOLYTA:
Four days will quickly steep themselves in night/ Four nights will quickly dream away the time

BENVOLIO:
I do but keep the peace: put up thy sword.

EGEUS:
With duty and desire we follow you.

DUKE ORSINO:
Give me now leave to leave thee.

VIOLA:
Good madam, let me see your face.

HELENA:
Never did mockers waste more idle breath.

JULIET:
It is an honour that I dream not of.

BENVOLIO:
Then she hath sworn that she will still live chaste?

DEMETRIUS:
Do I entice you? do I speak you fair? / Or, rather, do I not in plainest truth?

OBERON:
Hast thou the flower there? Welcome, wanderer.

VIOLA:
With adorations, fertile tears / With groans that thunder love, with sighs of fire.

BENVOLIO:
Be ruled by me, forget to think of her.

ANTONIO:
If you will not murder me for my love, let me be your servant.

NURSE:
Go, girl, seek happy nights to happy days.

ROMEO:
Is love a tender thing? it is too rough / Too rude, too boisterous, and it pricks like thorn.

SEBASTIAN:
I pray you, let us satisfy our eyes / With the memorials and the things of fame / That do renown this city.

LYSANDER:
I had no judgment when to her I swore.
