Green Day front man Billie Joe Armstrong says his sagging pants cost him a seat on a Southwest Airlines flight. The singer-guitarist for the San Francisco Bay area band sent a message to his Twitter followers on Thursday expressing his indignation at being tossed from an Oakland-to-Burbank flight for wearing his trousers too low." Just got kicked off a southwest flight because my pants sagged too low! What the f---? No joke!" he tweeted. An ABC7 news producer who was on the same flight told the station that a flight attendant approached Armstrong as the plane was getting ready to take off and asked him to hike his pants higher. The producer, Cindy Qiu, says Armstrong initially responded by asking the attendant if there weren't "better things to do than worry about that?" Let's all pitch in to buy Billie Joe a pair of suspenders.
