Generally, what are the rules I should look out for?
"Holy shit!" - When I wake up the next day itching from crabs. I don't think this would violate the rule. As I'm not actually invoking any spiritual being in particular.
"Oh Jesusjesusjesusjesus!" - I might exclame as I apply copious amount of lindane to the infected area. Sorry Jesus, I think I might have to say I'm sorry for using your name here.
"Thank God." - The crabs are gone. What's wrong with praising my higher power now that my affliction has passed?
"Fucking Christ shit balls, ow ow ow" - I was napping on the beach and a crab latched itself onto my sensitive bits. This might cross the line and I should probably report to confessional.
Feel free to extend this discussion into doodles I might be drawing of Muhammad while sitting in the emergency department.
