"If You're Happy and You Know It" is a repetitive children's song. It has, like many familiar childhood cantations, been altered in various ways over the years for various uses. After time is reversed in "Yug Ylimaf", a deleted scene features Stewie not looking forward to experiencing the "Mommy & Me" class with Lois all over. A cutaway has Stewie inserting his own personal feelings about singing with Lois.
