Believe it or not, the first version of the song "'Winter Wonderland" I ever heard was the parody version that goes, "Walkin' round in women's underwear." I believed for the longest time that the "Women's Underwear" version was the correct version and everyone who sang "Winter Wonderland" had just misheard the lyrics.
