(Seeing Mike and Carol in their costumes)
Alice: Sonny and Cher?!
When Mike and Carol were showing Alice their party costumes, they asked her who she thought they were going as. Sonny and Cher were a singing duo in the 1960's with hit songs such as I Got You Babe, Baby Don't Go, and The Beat Goes On among others. They also had their own variety show in the 1970's.
