Yet another Myers-Briggs thingy - at least I'm consistent! (i.e., I've always got the same results).
The good news: Elizabeth II of England is an ISTJ, too.
The bad news: So is George H. W. Bush! (which is better than George W., but not that much)
I do take a little bit of offense at the idea that Cliff Claven of Cheers is an ISTJ, though! And Puddleglum, from the Chronicles of Narnia - granted, does kind of save them in the end, but he's not what you'd call a fun and exciting character!
So, yet again more results that make us ISTJs look incredibly dreary and dull...
