Weezerpedia:Today's featured song/June 21, 2009
"Say It Ain't So" was one of the original Weezer songs to be written. Originally, Rivers had written all of the music and had only the line "Say it ain't so". Rivers made the connection between the line and an experience he had in high school where he came home to find a bottle of alcohol (belonging to his stepfather) in the refrigerator. Rivers recalled that around the time his biological father left, he started drinking. He began to fear that Stephen, his step father, would soon leave his mother much the way his father did.
