One morning in the early 90's I was laying in bed before school, listening to a Cleveland-area morning DJ on my clock radio. He was discussing how "Rapper Sir Mix-a-Lot was touring the country with his giant butt balloon to promote his song '"Baby Got Back (I Like Big Butts)." But he misread the copy as "Baby 'I' Got Back," and when the parenthetical was also not explained, the way he read it made it sound like the song's title was: "Baby, I Got Back. I Like Big Butts."
So upon hearing that, I pictured the premise of the song being that some guy arrives back home from a trip (see pictured), and defiantly yet cheerfully informs his wife that his journey gave him a new perspective on things, and upon his return he's realized that he "likes big butts," and perhaps this unfortunately changes the dynamic for them as a couple.
