Last August I presented a class on "Intimidation" to the staff of the library. One of the things I passed out was a drawing similar to this picture.   It's one of the most intimidating stares I know of -- sort of a "you're interesting, but of little consequence because you're too big for lunch" sort of thing.

My wife bought me a long-sleeved tee shirt at the Sitka Raptor Center with this view of an eagle on it. Underneath it says "I AM smiling!"
