Many Greek plays have a large theme of three as do Shakespeare's plays.

And there's a sub-genre of Gaelic satire called 'triads' (not like the Chinese!) in which things are threed; a famous one (I can't find the original in Irish, but if you're desperate I'll ask around if you PM me): "Three things that are costly to an Irish person: the hoof of a horse, the tooth of a hound, and the smile of an Englishman."

Another: "Bean bhreá nó capall bán nó tigh ar ardán: sin trí mhallacht an clutharacháin" - "A lovely woman or a white horse or a house on a height: those are the three curses of a leprechaun".

The holy trinity (Father, son and Holy Ghost), or the Pagan trinity (Maid, mother and crone).
There are the three stages of life (as some crudely put it hatches, matches and dispatches meaning birth, marriage and death).
There's also a rule of three in comedic timing, where you should always leave your funny thing until third in a list of not funny things because that will make it funnier.
There's a good novel, which I'm actually reading at the moment, called "Instances of the Number Three" by Salley Vickers, and there's a quote from teh philosopher Bertram Russell about three in the front, which unfortunately I've left at home -- you could try Googling it, though.
There are the three witches in Macbeth, the three sisters in King Lear, I'm pretty sure there are also three Merry Wives of Windsor, and three marriages in The Taming of the Shrew.
I was about to say three Die Hard movies, but there's another one now, isn't there?
Three months in a quarter, three chemical states of being (Solid, liquid and gas), three grammatical stages in a sentence (Subject, verb and object).

Hopefully that's enough to be going on :)

BLAH, forgot the three graces: Hope, Faith and Charity

And, of course: Two's company, three's a crowd :D
