Spread eagle

L: Why is it called spread eagle anyway? I don't even think an eagle could do that.
B: I don't know. Wings out, legs up, feathers to the sun. I could see it.
L: Trust me, a bird is not going to be able to get in that position. At least not alive anyway.
B: But how do you know? Are you an eagle expert?
L: Um, no. No I'm not.
