My dad has a pretty cheesy sense of humor and he would buy at least one cardboard fireplace every year around the holidays. Each time he would find a way to turn it into some kind of joke. We actually had a real fireplace and used it frequently but that never stopped my dad from buying fake ones.
One year he put the fake one right next to the real one. Another year he put 6 or 7 or them in the same room. Another year he put a few on our front lawn. He got such a kick out of it.
