Not very folky, but my wife, it turns out, had for years and years misheard the following line from Winter Wonderland: 'Later on we'll conspire/as we dream by the fire'. She heard it as 'Later on we'll perspire....' etc.

When put right, reason did insist to her that there was nothing particularly romantic (or logical) about sitting by a fire sweating horribly with your dearest loved one next to you doing the same thing. You could, after all, take your pullover off or move to a seat further away to carry on dreaming.
