Sallisaw, oklahoma 

What the heck is this place. A city in Oklahoma with like five people, where everyone knows everything about you and can't seem to stay out of business. The home of the Black Diamonds and thirty minutes away from Fort Smith, AR.

So have you ever been to this place they call Sallisaw, Oklahoma?

Sillyism 

Sillyism is a holy religion THAT IS TO BE RESPECTED and the point of the religion is always to be silly

the religious text states:
1. Be Silly whenever humanly possible

if you want to join first you MUST subscribe to Max Fosh then raise your right hand then put your left hand up and wave them like you don't care then you must repeat after me I swear that I will be silly for the rest of my life. I swear that I will sit at the front of the bus and pretend like you are the driver. I promise if your friend puts too much sugar in their tea you must reply do you want any tea with that sugar. I promise to make all dental appointments at 2:30. I am a silly billy, I eat silly sausages I promise that I will be silly at every opportunity.

Person 1: What religion are you?
Person 2: I am part of sillyism
