When I studied the play "Much Ado about Nothing" in High School, my teacher told us that the word 'nothing' was pronounced 'no-ting', making it a homonym for noting (noticing). It's a cool pun in the title of the play, if she's right. Almost all the drama in that play is caused by someone seeing one thing and interpreting it as another - sometimes by design.

Plus it has possibly the best line in all of Shakespeare:
Dogberry: Oh, if only the sexton were here to write down that I’m an ass! Gentlemen, remember that I am an ass; even though it’s not written down, don’t forget that I’m an ass.
