Breaking up is hard to do, but if your last date is at the Rock and Roll Hall of Fame, at least you can see a lot of cool exhibits with (or without) your soon-to-be-ex. If you're the one who's taking a little piece of their heart, swing by Janis Joplin's exhibit to see some letters she wrote to her loved ones while on the road. If you're the dumpee, take a walk with Elvis down Lonely Street. Have a snack at the museum's café and cry into your cherry pie. Yeah, yeah -- love stinks.
