"Like, Her Majesty's bodyguard - Renata - she's dull as a post. She can, say, find prime numbers in her head better than some computers and better than any human even if you give the human pen and paper, but that's not smart, she's still dull as a post. But she's a post with lots of room in her dull-as-a-post head to fall hard for some dull-as-a-post mate if she ever runs into the right person."
