What's up with people having those Dancing Milk Carton avatars. I look at the Top 5 Users and I see the top 3 all have that knid of avatar. It's not that I don't like it ... it's just that it's wierd that 3 people have the same kind of avatar (not the same avatar .. but similar)

So I was wondering why people like that kind of avatar? Am I the one who has noticed this?
