Does Dogberry and his constables provide humor in Much Ado About Nothing?

        For a drama to be a comedy, it has to have some sort of humor in it.  One may ask what humor is.  Well according to Wikipedia, humor is the tendency of particular cognitive experiences to provoke laughter and provide amusement.  The question is asked as to whether or not Dogberry and his constables provide humor.  Well in looking at the definition of humor, it can be seen that both Dogberry and his constables provide humor in the book Much Ado About Nothing.  I, however after having read the book and watched the movie fail to see much humor from these men.  Instead of being humorous, I saw these men as a group of dump men with the dumbest being Dogberry himself.
        For instance, in Act 3, Scene 3 when they chose the men that were going to be the watches for the night and Dogberry is explaining their roles to them, he says "if you meet a thief, you may suspect him, by virtue of your office, to be no true man: and for such kind of men, the less you meddle or make with them, why the more is for your honesty."  He then goes on to say "Truly by your office you may, but I think they that touch pitch will be defil'd: the most peaceable way for you, if you do take a thief, is, to let him show himself what he is, and steal out of your company."  This happens to be quite stupid.  To me, he is trying to say that because these men are constables and watches they should be able to spot a thief.  Nobody can suspect a thief because anybody can be a thief.  He then says that they shouldn't trouble these people but to be sure that they are really thieves, they should allow them (thieves) to steal from them (the watches).  Only a dumb person would give advice such as this.  This was obviously suppose to be funny but in truth it only showed how dumb these men were.
         Another part in the book which proves that Dogberry and his constables do not provide humor but that these men are actually dumb is in Act 3, Scene 3 lines 15-18 where Dogberry says "God hath blessd you with a good name: to be a well-favored man, is the gift of Fortune, but to write and read, comes by nature.  This is a pretty dumb way to put things.  Its not humorous at all.  'Well-favored' means handsome and so in all he is saying that 'to be a handsome man is a gift of Fortune, but to write and read, comes by nature.  Do you find this funny? I doubt that you do.  It seems rather dumb that a constable would say such things, since to be a handsome man is a gift of nature and to be able to read and write is a gift of fortune.  Someone is fortunate that they are able to read and write, it is not a gift of nature.  Once again showing how dumb these men were.
        In concluding this essay, it can be said that Shakespeare's idea to write the characters in such a way was to make the play humorous.  This may have had a positive effect on some people but as for me, I don't think that they were humorous.  I saw them as a dumb group of men who did and say the things they did, not really to make us laugh but because they knew not how to do what they did without seeming dumb.
