Soccer tricks.
Or any other kind of entertaining skill that hands itself to street performance art, for that matter.
Whenever you see someone performing in the city, doing stuff like this…

If you do, don’t be one of those dismissive snobs that goes “Phhhh, I could do that.”
No. You can’t. Show the artist some respect.
