I just came across this on Craigslist. For some reason, I find it really funny.
Oh, bummer. He must have taken the listing down after I originally posted the link. It was a couple pictures of a not-so-nice looking white goose running around outside and the ad read something to the effect of, "Free Guard Goose. Not a good pet. Not good with children. Not good with anybody. Just a good guard dog (goose). Needs to go soon."
