Caza de carroñero desnudo

I was visiting a friend for a couple of days. One day she went out to get groceries. I quickly saw my chance to "run some errands" too ;-) and that is when my 1hr+ journey to find all the "treasures" started ! I had to be as quick as possible to be back before my friend would come home, how would i explain that i was out with the car while being entirely naked?!?!
