There was a group of clowns in the People's Joy Parade who got something to eat afterwards (clowns get hungry, too, although you'd never know it) and hung around during some of the Cinco de Mayo festival. I'll have more but I particularly liked this one. S/he seemed sad/not sad, or maybe just pensive and observant. I like all the ambiguity.
Being an opera fan, clowns often make me think of I Pagliacci . Put on the costume and make people laugh, even if your heart is breaking. https://youtu.be/-kbi1EMcD3E
