Lol Id better think of some good idea for a random thread to join the trend.
keys, phone, loose money, cancelled bus tickets (too lazy to throw them out, lol), hex keys (you never know when you'll have to tighten something on you scooter, even if you're not riding it at the moment), something to tie down my hair (sometimes really random stuff like a wire or a bandage that we had to bring for first aid classes), pieces of a broken CD which is what I use as a guitar pick and sometimes other junk.
