You get to decide where you are and what your antic is
For example, if you know polka, you can play polka music in front of Czech people. If you know how to sing, you can sing your favorite anime song in front of Japanese people. If you know Tai chi, you can do it in front of Chinese people.
Try not to do things that will get you in trouble with the law, such as singing Nazi songs in Germany or K-pop songs in North Korea.
Also try to actually know what you’re doing. Something that you’re pretty proficient at, because obviously you don’t want to fuck up in front of other people, especially strangers that may or may not take a poor performance as an insult to their culture.
anyway. uhhh. nothing. i have no unique skills of value. why am i sitting in a sea of foreigners. where am i. o god i don’t speak the language. i don’t have a passport. shit
if you’re singing the popular kpop you gon’ die doing this in North Korea, no joke
Put on a yellow and black costume, go to Ancient Egypt with your casual time machine that you may find laying around in an alleyway, and pretend you’re a god.
