One of the unique sounds of La Paz is the typical response to absurd statements and ironic jokes: Yaaaa!
Tune your ears when you visit, and you’re sure to hear it all around town, uttered at times by individuals but most gloriously expressed in the collective humor of groups. When a bunch of adolescents are on a roll, the responses tend to crescendo– you may not hear the joke but the Yaaas! will ring out a block away!
I wish I had a good video so you could hear it. The intro to this quirky little song (a tinku, which is not from La Paz) is the best I came up with in a quick internet search. But really, you should come hear for yourself.
