I was just playing MO and I found this really funny thing. When you possess a glukkon walk up to the Lulu Fund and donate your moolah. When the maximum amount goes over the glukkons head depossess him (you have to be quick). Then you will have opened the exit and the gluk will still be alive! You can possess him again and he is all out of moolah! When you depossess him for the 2nd time he starts screaming about his moolah then he passes out. I found this quite funny leaving them alive after losing all their moolah
Note: I have only tried this on the Brewery Chump so it might not work on others.
