Pop Goes the ?

Today we were running errands and we were listening to a cd of kids music in the car. The song that was playing was Pop Goes the Weasel. At the end of the song, Alley said, " Is that "weasel" like you draw on?" I explained the difference in "easel" and "weasel" while I was wondering what she must have been picturing in her head as she sang this song!
