Shakespearean Fools!

Hello everyone!

I'm a 22 year old student from Belgium and I've decided to join this forum because this year, I have a class on 'Shakespeare and the Middle Ages' and for my oral exam, I've decided to do an oral presentation on a few Shakespearean fools.
However, because I do not want to be too theoretical in my approach, I thought it would be a great idea to see
how other people (other than actual scholars who did research and stuff) see some of the fools in Shakespeare's work.
I reckon that your visions and ideas might help me to build up something interesting and original for my oral presentation.
The fools I am supposed to analyze are Lavache/Lavatch from All's Well That Ends Well, Pompey in Measure for Measure, and Launcelot Gobbo in The Merchant of Venice.

So if you guys have anything to say about these particular characters (or the Shakespearean fool in general), FEEL FREE TO DO SO !

Thank you !
