I know this, because there was a song called '98.6' when I was young - it is a very old song - which meant that, when I was told in Biology that it was 98.4, I actually processed it ("Wait, what, that song lied to me?!"). Mostly all that happened to me in Biology is that sometimes the teacher would say 'Capillary' and I would jump because I'd think she was talking to me.
