I go to the gym at work and start milling tread and break a sweat. Then I realize I've brought dirty gym clothes to work. I smell so bad I apologize to the treadmillers around me.
Then I take a shower and feel and smell clean. Then I dry off with the towel.
The dirty towel, which gets wet from my skin and releases scented man-crystals.
At least I'm going to the gym. I have proof.
