I'm a little saddened. I had the 2-Riffer version, bought the 3-Riffer version expecting all of Fred's riffs replaced with all new riffs, but heard a lot of Fred's riffs still there, (did he say "mu-pet"?). Sure, they were funny the first time, but there is just something about Fred's personality that adds a different dimension. I know he might not have written all his own riffs, but it seems like he "owns" them now. It is like hearing a comedian doing another comedian's material, it automatically makes it sound forced or cheap.
