My personal favorite is Sonnet 130. Very traditional Shakespearean sonnet, in that the couplet at the end offers a twist on the three previous quatrains. I think that number 18 "Shall I compare thee to a summer's day..." is the most quoted and well known of his sonnets.
"Shall I compare thee to a summer's day?" is probably most recognised a being his.

sonnet
Probably either Sonnet 18 ("Shall I compare thee to as summer's day") or Sonnet 116 ("Let me not to the marriage of true minds admit impediments")
I know it was his most famous.
Romeo and Juliet
It is a line from William Shakespeares Hamlet. Most of William Shakespeares plays are still famous now as he is regarded as the greatest writer in the English Language.
