One of my favorites is how amazing a habitable planet is.
Haha, yeah. I just love that - clearly the planet was made for us since it's so perfectly suited to our needs! Umm...if we had adapted to the environment that we live in for roughly 4 billion years, you'd expect our needs to be pretty closely aligned with what's available...
I once likened going to the meetings every week to being stuck in the 5th grade for your entire life. My wife didn't react too favorably to that comment.
