I hope i'm posting in the right place, I just felt I had to share this.
Just a couple of minutes ago i was reading something about an abdominal exercise that included the word "perpendicular". I asked my dad ,who was sitting at his computer, what it meant, and without missing a beat he spun around in his chair, looked me dead in the eye and began chanting
"in days of old
when knights where bold
and ladies weren't particular
they stood them up
against a wall
and fucked them perpendicular"
He rotated his chair back towards the computer and mumbled "means "upright".."
