My birthmother carries a small package of marbles. she claims it's so no one can say she's lost hers.
The oddest thing in my bag currently is an expandable grocery bag, which is not really odd. Or the folding pair of scissors.

How come?

A tiny miniature ouija board. I made it in 1987, when I was thirteen years old and a ouija board freak. It's kind of scaring me that I've been carrying this thing around with me for almost twenty years.

My usual bag is either the day-glow yellow messenger bag I take to work or the pirate booty bag, both of which are weirder than anything I carry inside them. Unless you consider carrying a knitting project everywhere you go weird. (-:

I don't know, I'm sure there's a lot of competition from both inside and outside the backpack. Maybe the (Harry Potter) wizard coins can have the title for today.

I always carry a face mask with me just in case I might be where there are a TON of sick people. But mine has little kawaii things stiched on it, like a panda, 4-leaf clover, or bunny.

A human tooth? If not that, probably the fairy ball.

A tuning fork. I got stopped by airport screeners because of it once. Or maybe it was because I had three of them. They seemed to think it was a giant roach clip.

A small rock from Puget Sound

My notebook. It is not, in itself, intrinsically weird, but some of the notes contained within it are exceedingly random...

About a dozen vials of BPAL in all scents.

Or maybe the measuring tape on my keychain.

N.

Three knitting projects - but that's not particularly weird. Perhaps the tape measure might be a little weird...

Tobacco. I carry it in a little round metal tin that used to hold mints.

A friend of mine who's Native American talked me into watching the Jim Jarmusch movie Dead Man, and afterwards he kept asking if I had any tobacco. It's sort of a recurring thing in the movie. Has to do with dying and the afterlife and it's just a good thing to have. So I went out and bought some pipe tobacco, and I've carried it around ever since.

There's nothing really weird now, but I tend to wear out my fanny pack by accumulating way too many coins.

I used to carry practically everything in my bag, and it was rather heavy. A friend once said, "I'll bet you even have a flashlight in there?" Normally I did not, but by chance I had just put a huge flashlight in there for a specific purpose, and hadn't taken it out yet. I often thought about buying a toy kitchen sink just in case somebody said something.
