OK, we have a theory, let us know what you think: Where do all great ideas and interesting thoughts come to you? it's not during a casual walk on the street or during a hectic time at work, right? it's almost always when you're taking a shower, or when you're on the toilet, or sometimes when you're sitting at the beach looking at the ocean, right? so our theory is that it's the water! you either sit in water, above water, or next to the water when the really interesting thoughts come to you. therefore - thoughts are made of water!
ok, it might not be our best theory, but that is because we came up with it on the chair at work, there is no water here (Which further proves our point). Anyway, the people on this list must have gone swimming or something because this is a collection of deep intrusive thoughts that could only have been the result of sitting really close to water.
