(As Eric Cartman would say)
Heh, why don't ya commit a random act of senseless beauty and fix your bumper!?
Update: I'm a very bad person for making fun of hippies and other people with idealist bumperstickers. Furthermore, I'm a bad pilot for it, a disgrace to my airline. To make amends, I'll make the following PA tomorrow:
"Dear brothers and sisters, welcome to our bonding experience at 25,000 feet. As fellow laborers, we feel connected to you and are pleased to share the bounty of our all-natural food and drink cart with you. No payment is neccessary - in this commune aloft, every person gives according to their abilities and takes according to their needs, and money is simply a token of enslavement we must all reject. For the next hour, bask in the positive energy of this flying friendship vessel. Once we return to mother earth, make sure that you take your joy and your positive aura with you! Now, our esteemed group leader, Captain Doug, will lead us in a heartfelt rendition of 'We are the World' along with the controllers of Seattle Center."
