Four(!) Terminator bobblehead dolls
All the Osbournes bobbleheads including Ozzy, Sharon, Kelly, and Jack Osbourne.
X-men 2 bobbleheads including Wolverine & Nightcrawler
And when available: a cat in the hat bobblehead
I'm more concerned with finding new bobblehead information and interesting topics to cover, but will also add new nodders to the site when I see some I like.
