I keep it in a jar with my toe nails, dead pets and facial hair. But my mom says I'm a perfectly good boy.
When I was in my teens, I decided to collect my spunk in a mason jar. Everyday for about a month, I would pop off 2-3 loads a day. It had a pretty good amount in the jar....enough to swish around.
About 15 years later I was visiting my mother during Christmas break, she told me that she had moved all my crap from high school out and it was in a box in the garage. After opening the box, the first thing I saw was the cloudy glass of the mason jar. It brought a big smile to my face. Man....I miss my youth!!!
