When I was in 1st grade we would sing My Country, Tis of Thee every day after saying the pledge of allegiance. All through 1st grade I believed one line in the song-"of thee, I sing"- was actually "of B.I.C." I had no idea what that stood for, but since everyone else seemed to know, I thought I should keep my mouth shut. Once I saw the letters b-i-c on my dad's cigarette lighter, but instead of being a tipoff that my lyrics were wrong, I assumed it must just mean the lighter was made in the USA. It wasn't until 2nd grade when the words to the song were printed on the first page of our social studies books that I discovered my error- and felt like an idiot.
