The gym I used to go to had "How does it feel in my arms" playing every half hour. It started with arms, then the chorus had the line twice with a little delay so the s of one arms came right after the ar of the other. By the end of the song the lyrics become completely blatant but apparently no-one else heard them the way I did.
I leave you with my favorite jarjon acronym: People Can't Memorise Computer Industry Acronyms.
