I just finished reading Act III of Love's Labour's Lost. The use of wordplay in this particular play is excessive and takes a central role in the play itself. Often, the characters spend more time bantering and discussing their use of language than they do actually living life itself or moving the plot forward. But, this in and of itself becomes an important part of the story. I found particularly interesting in this act Shakespeare's use of language to contrast the fool of Armado and the passion of Biron.
