It's safe to say Bille Joe Armstrong did NOT have the time of his life on his last attempt to fly the friendly skies. He's the latest star - following Josh Duhamel, Brooke Mueller and Gerard Depardieu - to get booted from an airplane. This time, the offense wasn't disruptive behavior or a weak bladder. The American Idiot's pants were too saggy. Armstrong Tweeted, "Just got kicked off a southwest flight because my pants sagged too low! What the f***? No joke!" Eyewitnesses on the flight say a flight attendant approached Armstrong before the flight took off and asked him to pull up his pants. He reportedly asked if there were "better things to do than worry about that?" Apparently not, because Armstrong was forced to take the next flight - no word on whether he hiked up his britches for the Burbank-Oakland trip. Southwest seemed to make things right after getting word of the incident. A spokesperson said, "As soon as we became aware of what had happened, we reached out to apologize for this Customer's experience," the statement read. "He elected to take the next flight. We followed up with this Customer and involved Employees to get more details and, in our latest conversations, understand from the Customer the situation was resolved to his satisfaction."
