What do people hide under their foreskins?

You know, a foreskin! The extra skin at the end of one's penis. I was circumsized at birth so I really want to know what people hide under their foreskins. This one guy said he once hid skittles under his foreskin and ate them in class, even shared them with his classmates! ( what a nice thing to do!) But what is the most common thing to hide under it? If your going to prison do you hide a shank under your foreskin? if your going on a hike do you keep water under your foreskin just in case you get thirsty? Can you put popcorn in their if your watching a movie? All of these sound like great advantages.
