<----  I am this guy, and the other is a lemming.

I chose this because I have a good working reputation with this lemming.

you look a lot more pale than I expected. And your bright green hair that is an unusual choice; but I support it, to each his own.
The Lemming that is holding you, for some reason looks an awful lot like a human to me

the guy in my avatar is "Moondog":
Louis Thomas Hardin (May 26, 1916 – September 8, 1999), better known as Moondog, was an American composer, musician, poet and inventor of several musical instruments. He was blind from the age of 16. In New York from the late 1940s until he left in 1972, he could often be found on 6th Avenue between 52nd and 55th Street wearing a cloak and Viking-style helmet, sometimes busking or selling music, but often just standing silent and still.
