Aside from the fact that Jeff Tweedy would probably be paralyzed with fear to be in the presence of Bob Dylan, it would still be pretty cool to listen to a song these two worked together on. If Dylan listens to his son Jakob's band The Wallflowers at all, odds are he'd be pretty down with Wilco stuff too. It's easy to think that Jeff is good at guitar or poetry until you put on an old Dylan record, but it seems like Tweedy is the type of person who rises to the level of whatever is around him. Stick this guy next to Bob Dylan and who knows what he'd come up with in an effort to impress the bard. Related: Bob Dylan would never pull a stupid stunt like this... although he WOULD allow appear in a Victoria's Secret commercial with Adriana Lima. Priorities.

6. A jar, with a heavy lid.
Possibly the best Wilco song on earth and a personal favorite, so I had to drop this in sorry guys LOLZ. But this is a great opportunity for you if for some reason you never listened to Summerteeth and you're in the mood to hear an incredibly beautiful, very sad song.
