AAAHHHH I LOVE popping bubble wrap!!!!!!!!!!!!!!
another great childhood packaging pasttime? those little styrofoam peanuts

many a time did I leap into boxes full only of those and throw them up in the air like snow and roll around in them (only to find that they had been squished into the carpet and I had to spend just as much time vacuuming that shit up as I spent playing it it

)
plus just any form of empty box. It's like freaking Christmas; don't even get me a present, just send the old box your refrigerator came in and I'll be happy as a clam. seriously.
