An "out-of-character" moment for Lincoln?

[LincolnMan]

Forum members, help me out on this one: it seems to me (speaking of "an out of character moment for Lincoln") that there was a story of young Lincoln and a buddy sewing a racoon skin on a dog after a "coon hunt." I believe the dog was then killed by another animal- thinking the dog was a racoon. Anyone familiar with the stroy? Where is the account found?
