Answered in the style of Pedro...
I wore the sad clown outfit as a representation of Roger Waters. The white paint symbolizes his desire for purity in his art. The sadness is because none of the other members of PF, David Gilmore in particular, wanted to admit that he was a genius and far superior to any other artist, ever.
I can completely relate because I am also a misunderstood genius movie reviewer, poet, and forum poster. Pretty much just like Roger Waters and David Gilmore combined, except instead of music or lyrics, I write fantastic forum posts.
You may ask. Why do I waste my time with people of such obviously lower intellect than mine? Simple. I need to show you and teach how dumb you all are by making extremely obvious, long winded, observations.
For example (insert obscure person from the 70's) once said that my movie reviews where much better than watching the movies themselves. Given the type of artistic movies I am into, that's probably true.
Pedro, I kid. Your posts are awesome. Never change. Stay golden, pony boy. :) :)
