When I was a in my teens, I used spray deodorant. At the time I was still building model cars too. (Don't get ahead of me). One bleary morning I grabbed a spray can of model paint instead of my deodorant. :

Sprayed both pits then the smell hit me. Looked in the mirror, I had sprayed them bright orange.........

I moved my deodorant to the other side of the room after that.
