Hoobastank?!
My university sponsored a free concert in the town center about six years back or so. They got Hoobastank to play. Dude tries to propose to his girlfriend during "The Reason," gets interrupted by some other guy running into him, then gets interrupted by the lead singer who called the couple up onto stage. The guy finally finished his proposal, the girl said yes, and everyone clapped. Lead singer hugged them and sent them back off stage and said, "That was great, I'll see you guys next week at the wedding DIVORCE!"
