Green Day singer and guitarist Billie Joe Armstrong says his sagging pants got him kicked off a Southwest Airlines flight. "Just got kicked off a southwest flight because my pants sagged too low! What the f***? No joke!" he tweeted. An ABC7 news producer on the same flight confirmed the incident, saying an attendant asked Armstrong to raise his pants. Armstrong asked if there weren't "better things to do than worry about that?" After going back and forth about the the pants with the attendant, Armstrong and his companion were taken off the plane. Southwest says they apologized to Armstrong and put him on the next flight.
