We've all been to a game-con or an analog at some point. What's some random swag that you still actually use? It could be a shirt - almost all of my swag game shirts are now my work/gym shirts, which is convenient.
I also just found a keychain I haven't seen in a while, and while there's plenty of goodies on it (nameplate from friends in Hawaii, small light) there's also a... Brutal Legend flat figurine. That sure was something.
Also, pics = props.
