There is an opportunity for mischief here!!!
One time I fly down to my brother's place for a fishing trip.
It so happened that an old high school buddy of mine had left his truck there while he was in Costa Rica surfing.
So......we opened the ruck and went through stuff; among other things, there was a digital camera in the glove box and a bottle of "Scope" mouthwash under the seat.
I did what any good friend would do.
I jammed one of my testicles into the opened scope bottle and took a picture with his camera...then put everything back.
We thought it was real funny........he was kinda pissed. I am guessing he used the scope before he downloaded his camera card.
