Andrew Bird's music video for "Give It Away" features a Piñata Man who "plays" children's birthday parties. Piñata Man is obviously in the wrong line of work.
I'm sure this is a metaphor for something. Something. Also, it wasn't just your mom who was nuts growing up.
"Give It Away" is off of "Break It Yourself," a title which seems to have some bearings on piñatas everywhere. The album was released earlier this year.
