I had a roommate that, without thinking about it, referred to an ex-girlfriend as "larger than man-sized". He didn't even realize it until we pointed it out to him what he had just said.
There was a thread like this about EverCrack once, and someone commented that he was going on a long road trip with his family, and he was thinking to himself that it would be a long drive, but then he corrected himself mentally and thought "well, I could drive there, and then I could just teleport back to my bind spot."
