When is the last time you changed your avy/ sig?

My avatar I've had probably going on three years now. Started using it when I was in to WoW and just never bothered to change is since. My sig however is a new one I just made yesterday.

I changed my avatar just a few days ago because I was getting bored of it.

About a month ago, I change it often but I always fall back on this combo... it just feels right as I've had it for so long.
