Youssie, awww, I don't think he was a troublemaker, I think he just got alittle confused but I do believe that he always meant well. When he orchestrated that burrow move, he really believed he was doing a good thing. I do miss him!
In my heart of hearts, I believe that Yossarian and Shakespeare are out there together watching everything that is going on. Yossarian, without a doubt, knows his brother (Zaphod) well. In your mind's eye, you can just see them plot- ting and scheming on the best way to come in under the "radar" and undetected by the Sean Connery of the Kahalarai (Zaphod). In case you haven't noticed guys, there is a shorage of suitors in the Manor.
youssy actualy became short-term dm at lazuli with wingman zarathrusta. They performed a coup while the lazuli boys where away but unforchantly they returned and youssy and zarathustra where thrown out following a beating. zarathrusta went back to whiskers but youssy went his seperate way and is 'last seen' wouldnt it be great if he, like these wild groups that appear on the manor, just appeared again one day with his own group!
