Historically here have always been two major debates around shitting:

Q: Which way is the correct way for toilet paper to hang on the roll?

A: Over the front. If you're a civilized human-being this isn't even up for debate. For those of you who don't believe that this is objectively the truth, may I submit Exhibit A: 

This is the original patent for the "toilet paper roll." Checkmate. 

Q: Do you wipe from the front to back, or the back to front?

A: Side to side. 

Since those longtime topics have clearly been settled, there is only one last hurdle to cross before we're conflict-free when it comes to the toilet. 

Q: Do you stand to wipe your ass or do you stay sitting? 

Are you one of these guys?

Or one of these guys?
