Exercise - do eyebrows count?

I sat on the exercise carpet, pulled the soles of my feet together and willed my knees down.  Then I caught myself in the mirror, and for five minutes exercised my eyebrows up and down.  Listening to the music I tried to make them synchronise to it, I thought of doing an eyebrow Mexican wave.  Tried it a couple of times and just couldn't pull it off.  Nearly but not quite.  Next was to try and create a Uni-brow by frowning hard but nope, those thick caterpillars didn't meet up.  By the end of the track I then realised eyebrow exercise doesn't count in the gym and wouldn't result in a sweat. However, I'm sure there must of been the odd calorie burnt.
