To the person who’s been directed to Uncle Crappy twice in the last few days while attempting the following search:

Wilco lyrics “I don’t know why this happened”

I think the line you’re looking for is “I have no idea how this happens,” from “You Are My Face” on Sky Blue Sky. And from a Volkswagen commercial.

Have further questions about Wilco lyrics? A Sea Black with Ink seems to have a pretty good handle on the answers.
