something you can ask your friend (too lazy to make up a good title)

so the next time you're with your friend,
1) hold up both your hands and ask "do you know which hand is right and which hand is the left?"
2)after he/she answered, ask this question "which hand do you use to wipe your ass after taking a shit?"
3)ask "are you sure?" after he/she answered either left or right
4)make sure they say yes then say "because we usually use toilet paper"
5) proceed to make fun of that person and judging by the surroundings you might not speak to that person for a long time
