Waste some time with me!

Somebody who obviously thinks I have a lot of free time on my hands sent me a link to this word-association game called Funny Farm.  I've been working on it for three days and have roped several of my co-workers into helping me.  We are reaching the limit of our knowledge.  Yes, I know that I could just merge with someone else's game and get an instant solution, but where is the fun in that?  I like little hints, not big spoilers.  So get to work, my loyal fans, and find me a five-letter word that connects Hell's Angels and Scientology!
