Besides keys, of course. Although if you want to say how many keys, go right ahead.
I have:
5 keys
Syracuse University lanyard
Gran Turismo 3: A-spec keychain (reverse side says “The Drive of Your Life”
Miniature San Jose Sharks goalie mask
CVS ExtraCare tag
I’m sure people have tons more stuff than me. Whatcha got?
13 keys
A St. Christopher medal (A silly thing for an atheist to have, but if I take it off and have a wreck, my Mom would never stop with the “I told you so’s”, since she gave it to me when I started to drive years ago.)
A pewter Snoopy dressed as the WWI flying ace, a gift from my sister.
A GI can opener that belonged to my Dad.
3 keys and a Guinness bottle opener (it finally came!).
eight keys (one for Kryptonite lock)
bottle opener (gotta have it)
squishy eyeball thing that “gooshes” blood and makes a disgusting sound.
clown when squeezed his eyeballs pop out
Bart Simpson showing his butt
one of those things for your keyring that whoever finds them can put them in the postbox and they will get sent to Stanford Blood Bank. Who will then call me. One Gallon Donor, Baby!
I have a keychain that has a red light and 4 key rings on it.
I have my house keys
My Parents appartment key
an Elevator key (Allows me to have me own personal express elevator. 
)
Car keys
and an illuminating Lightsaber from the JK2 game.
Five keys (house, storage garage, parents’ house, in-laws’ house)
Miniature Victorinox Swiss Army knife
Giant Food Stores Bonus card
Small blue Krypton flashlight advertising PowerStroke Diesel engines
The keys to each of my cars are on different fobs: Outer Banks lighthouses for the Buick and station wagon, and brand logos for my Taurus and Cadillac.
Five keys:
[ul]
[li]Parents’ house key[/li][li]My apartment key[/li][li]My car key[/li][li]Friend’s house key[/li][li]Friend’s mailbox key[/li][/ul]
One ‘Wisconsin Dells’ key thingy with my name on it, given to me by Joey Hemlock, and one metal ‘Peterbuilt’ key thingy.
5 keys, one for a small lock that I keep on my “electric box”. (A metal box like you’d see on a wall with, y’know, electrical thingamajiggers in it. Only, this one I found in a trash can in perfect condition, and now it is used to store letters and such.)
The purpose of one key has long since been forgotten, but I keep it around in case I ever remember and it turns out to be important.
Miniature faux Swiss-army knife.
Guinness bottle opener. (Doesn’t it just rule, Ferrous? I love the thing.)
Car key. 2 house keys. 3 office keys.
Steel plate that was put in my forearm when I was a teenager and removed a year later. When it was removed I asked to keep it.
Seven keys, house, truck, truck toolbox, briefcase, desk, 2 suitcase keys, the P-38 can opener that I brought back from my '68-'69 S.E. Asian vacation, a “World’s Greatest Dad” bottle opener, and the quick release pin that connects the half of the key ring that I carry, to the other half.
3 keys (One which I’m not sure what its for)
A maglight that doesn’t work
Fold up scissors
Radiator key
egg
Besides keys there is just the remote for my car and a Guinness Flying Toucan (actually I think it can be used as a bottle opener in a pinch). I usually have a small swiss army knife, but stupidly I forgot to take it off when I had to take a flight last week. Confiscated.

)

A broken key chain that says, in cut-out newspaper letters, “Give me all your chocolate and nobody gets hurt”…which is appropriate because I work for Godiva.
Keys (including keys to my old apartment and mailbox because they never asked for them back, and key to my mom’s house).
Grocery store savers cards (Randalls, Krogers, and Gerlands – I shop at HEB. Go figure.)
A little clippy thing that attaches my keys to the inside of my purse.
My watch. I can’t stand wearing anything on my wrist.

The rest are house keys, car keys, etc. Nothing special.
A brass tag given me by the favorite woman I ever worked for. (Gad I hope the boss isn’t reading this.) It once had the logo of the library where we worked, but it has been worn smooth.
Keys, a siver hook and a bulldog.
One key.
One mini flashlight.
One heart shaped gold charm engraved with J&L.
Many mini cards:
CVS ExtraCare

12 keys and a baby leatherman. My truck key, her car key, my truck tool box key, my house, her folks house, my moms house, two master lock keys for work, two keys that I have to give back when I’m done with my current jobsite, one for my closet in the basement that is never ever locked, and one to change the combination to the locks at work every time someone is fired or quits on bad terms.
The baby leatherman opens bottles in a pinch.
