Alright, alright, here's the story. This guy was a 'busker' using the old hook evangelical christian groups always use, which is to pretend to be doing something without any religious overtones to get passersby to pay attention - in this case, pretending to be a busker doing mathematical magic tricks. Half the audience was also composed of plants who'd ask the right questions at the right time, another tactic these guys always use.
Anyway, the audience was asked to call out numbers on the 6x6 grid of sequential integers between 1 and 36, and then he'd circle that number and cross out the remaining numbers on the same row and column. Before he started, he'd promised that at the end of the exercise he'd have the number 111, and sure enough, it turns out that no matter what combination of integers you choose you'll always end up with 111, after you add them up once all squares have been eliminated by either circling or crossing out.
He then proudly proclaimed that this was because there was Only One Answer, and said the same thing is true of the world. No matter what you do, there's only one true answer you can come to, and that's Jesus Christ. Flimsy, I know. The world is just a tad bit more complicated than a simple predetermined mathematical game, but that was his analogy and he was sticking to it.
The other stuff was a lesson about how the guy with no face is blue because even though he has money, a social life, a family, and goes to church, he has cancer and is dying and none of those things matter to him any more because he knows he is going to hell. The sIn clearly illustrates that "I" is a component of "SIN" (just like there's no "I" in TEAM, whoo! whoo! whoo!) and then he handed out some pamphlets.
We had an unusually civil discussion (for me) on how our beliefs and our stances on creation, evolution and the bible and the things we consider 'evidence' are fundamentally different. Then he gave me a kick ass Chick tract on evolution called "Big Daddy?", which like most things in its class horribly misrepresents the tenets of evolutionary theory, but of course some scientists don't treat religion any more fairly.
Earlier that day, some other people from the same religious group manning this same poster board called Jewish people "circumsized liars" which made me storm away, but this guy wasn't up to any of that so I kept my mouth shut and just listened politely, then discussed things with him afterwards and realized that there was no reconciling our views.
I love the monstrous, closed minded and intolerant scientist in here:

I've also got the poster version of that "Heidelberg man, peking man, piltdown man, blah" diagram on my wall, it's good for a chuckle and for getting weird looks from my lab-mates.
