#12: Confuse the US with Canada.
#13: Touch a random american.
#14: Attempt to enter an amusement park without paying. (And get banned for it.)
#15: Attempt to infiltrate the White House.
#16: Attempt to (illegally) dethrone Trump.
Btw, #9 kinds reminds me of the beginning of the first chapter of Final Fantasy XV. Have you been inspired on it?
Also, you should have named this "Yet 10 more things not to do in 'Murica."
It's still a cool comic, nonetheless. ;D
