Well, how about one of the few things I didn't have, the original piece of "Buffy the Vampire Slayer" merchandise. This 12-inch statue by Varner came out way back in 1999, years before I ever started watching the show or collecting copious amounts of Buffy merchandise.
I'd come across this a couple times in the past few years, but never took the plunge on buying it, in part because it was kind of hard to find the other two Varner statues (and I hate having incomplete sets). But my local comic shop dug this out from the back a few weeks ago, and when I was there today picking up my weekly comics, I figured the time was right to get it. This particular one is #122 out of 4,500, so it's a low-numbered one to boot.
Eventually I'll get my entire Buffy collection back online -- I managed to dig out all the pictures from my iPhoto library and start to get them organized -- but for now, this will have to do.
Happy Buffy-versary! What did your Watcher get for you?
