How to remove a cousin is very good but fell short of my top two.
Follow That Bottle might be my all time favorite episode....the concept of the old gang and such a silly plot just works so great in my opinion. This particular episode makes me consider how I want to live out my retirement. However, My wife thinks I am crazy!
Oh Look! Mitzi's Found Her Mummy is my other pick. Barry as the Mummy is great and in the end he had his shining, heroic moment.
