Linux advocate disguised as panhandler gives CDs away. Interesting social results: most people don't read signs, and panhandling is fairly lucrative. <wry grin>

Would be tempted to do something similar if I also had a stack of Ubuntu CDs.

Or—evil thought!—sneak into Microsoft dev event with button that
reads “Ask me about what I geek out about” and a bag full of Ubuntu CDs… ;)

(Convert the world one geek at a time! ;) )
