As this is just a new blog, I only have two candidates for my favourite quotes I’ve heard this week (i.e. not necessarily said this week!):

“Science works; planes fly. Magic carpets and broomsticks don’t. Gravity isn’t a version of the truth; it is the truth. Anybody who doubts it is invited to jump out of a tenth floor window. Evolution too, is reality.”
–Richard Dawkins, “The Genius Of Charles Darwin

“He has the memory of an irresponsible goldfish”
John Oliver, on “The Bugle” episode 41, in response to John McCain’s statement that “In The 21st Century Nations Don’t Invade Other Nations” (talking about the Russo-Georgian conflict)
