That being said, comparing him with Mercutio is really interesting. They're both complete pragmatists -- Falstaff's attitude towards honour in many ways mirrors Mercutio's toward romantic love. Now I must go and chew on this some more. ;)

Please do! I have been tempted to do an analysis and comparison of their characters and their relationships to their main characters for quite some time, but sadly I am out of practice in my scholarly pursuits when they do not pertain to my work.

And thank you. I enjoyed being Puck very much. I would love another chance to play him someday.
