Words can take on negative connotations over time, which can lead to misinterpretation of a song's lyrics. In this case, the offender is the word "midget," a pejorative term for a person with dwarfism. Al describes Barney Rubble, Fred Flintstone's neighbor, as "a midget but he makes a lot of trouble."
Yankovic told Lily Hirsch, author of the book Weird Al: Seriously, the term "was just sort of a jokey word and certainly not the slur that it's become... So I certainly wouldn't write a song like that now. Even when I perform songs that have that word in them, I wince a bit. And in fact, one time, I forget which city it was, but I stopped the song in the middle. I was like, 'Look, when I wrote this song, it wasn't that kind of word.'"
