I'M BATMAN! Or am I? Yes I am Batman...
I like your avatar. I do love a bit of batman though.
I like Doctor Who.
It also reminds me of myself when I am encountered with a challenge. I stop, think for a second, and get a look of duty over my face.
I think I've just had an epiphany. Your avatar reminded me of EvilFish1's a little bit, because of the eyebrows. Then I looked at your username. evilsqirrel. So we've got two evil animals, and they both have funky eyebrows.

It says...
Everything.

Those eyebrows!
My avatar is quite simple. I like TES. That, or I'm a God(dess).
