Anyone who says they have fun all the time is lying. In fact, they likely have fun none of the time.

Gimme a sec, lemme look up that one that a guy tried to get me to join. 
Of course there are also the really famous ones like Aum Shinrikyo and Koufuku no Kagaku. 
Actually, just a curious question, what do you consider to be the line between a cult and a religion? Not trying to be a fedora tipper or anything, its just something a guy trying to get me to join a cult/small religious group got me thinking about. Like, I don't really think of the Mormons as a cult. When I looked into this group before, nothing explicitly described it as a cult, but the way the guy tried to sell it to me very much felt like one.
