Dirty Jeans. Dir Tee Jeans.

When I was driving Dex home from pre-K the other day, I heard him singing softly in the back seat. "Dirty jeans, dir tee jeans."  I asked what he was singing.  He was quiet for a moment then said, "I can't remember the name of the band." I asked, "Is it AC/DC?" "Yes!" he exclaimed, "Daddy and I got AC/DC from the library." I remember when I first heard Dirty Deeds as a child and I, too, thought they were singing about dirty jeans.
