What's going on with this doll? It's Japanese *natch* and as far as I can tell it's based on a comedian called 'Egashira 2:50'. The 'fist in pants' pose (wonder what kind of Google traffic doozies this article is going to bring me...) refers to his 'Don!' catchphrase (see below). You can buy it here for 131 dollars.
The real Egashira action in action: (Don! scene at 6:15)
