Why do I still have these?

I have several different posts in various stages of completeness, but not enough motivation to finish them yet. So instead, here are pictures of random things from my past that I found while looking for something entirely different (that I never found):

My SmallDog customer card from 1998. Is it still even valid?


A casino card from my only visit to a casino...five (?) years ago.


An equipment lockout tag from an old job long ago.


Prepaid calling card? Wtf? How long has that thing been in my filebox?


A beer label I saved for some reason even though I never drink beer. Why did I do this?


My Northwest airlines customer card. I haven't flown Northwest in over ten years.


B. Dalton membership card. Man, I wish I had a chance to cash in the goods.


I don't even remember where this came from.


Lots of sex went on in that hotel.


St. Louis, arcade fun, killing zombies. Oh yeah, that was a great weekend.


There's far more weird things I found. I really need to throw stuff out.
