I've played Universal Paperclips from start to finish 4 times! I loved it. In fact, I loved it so much the last time around that I wanted to have another game "somewhat like it" in the background -- that's where the recent Cookie Clicker tab came from.
I always recommend Universal Paperclips to people who don't like cookie clicker games, because I fell in love with it the first time I tried it (heard of it from the Hello Internet podcast)
I'm not sure if this is still a thing, but at one point you could open up a JS console on cookie clicker and run game.ruinTheFun() to unlock everything. :)
I kind of feel like we need a "Year Zero" clicker game where once you get up to 1.7m "clicks" you'll see Pol Pot start dancing in the corner. Then as you accumulate more clicks, you'll see Hitler, Stalin, and Mao make appearances as well. Then, finally, once you've overflown the 32-bit integer, the year resets to 1970 and dennis ritchie and brian kernighan start dancing in the corner as well.

- HackerNews (the second source of addiction)
- Cookie Clicker (a rather recent addition that I'm slightly embarassed of)
At a point in time I also had facebook, but I've since stopped going there (maybe once a week).
