It's just that the eyes almost look like the one's they use for his. They have that creepy "real" look.
Annoying Orange didn't exist until many years after I set this avatar; so most likely not. Unless they stole it, too. They were from the avatar set of the first website I ever had an account on, mplayer.com (long ago, before it was bought by Gamespy): http://en.wikipedia.org/wiki/MPlayer.com
Are those The Annoying Orange's eyes in your avatar?
