LOL Hardway... The avatar comes from my earlier MW days when (surprise, surprise) there were a few sheep jokes floating around CSG. They were probably exasperated by me with the "modern day velcro gloves" and other quips 
When I stumbled into this picture (4 or 5 years ago? - big guess maybe more, maybe less) in an email someone sent me it just seemed perfect. It was originally a NZ Defence Force upgrade joke.
Since then it's also become my avatar for facebook too.
