You forgot the part where preachers are often heared adding their own interpretations as well.

I usually make fun of public preachers by telling them I am visually impaired and just letting them go on for hours, and only then telling them that the only reason I still see is science and no god. What they spout inbetween however is some of the most hilarious shit ever. xD

Also usually the point bystanders leave. Works every time. ^^
