Things that could bite you in the ass...

A good example of quotable things that you thought were smart but turn out to be really stupid ten fucking things later:

"It [LSD] opened my eyes. We only use one-tenth of our brain. Just think of what we could accomplist if we could only tap that hidden part! It would mean a whole new world if the politicians would take LSD. There wouldn't be any more war or poverty or famine."
*Paul McCartney, 1967*
