"Sing Your Synonyms" is a Sesame Street song sung by Maria and Luis. In this sketch, they portray a couple who visit an art gallery. While there, they each give the same opinion on various works of art, but use different terms; for example, Luis thinks that a big painting is tremendous, while Maria thinks it is enormous. Eventually, they argue over whether a painting is fantastic or terrific, leading the various pieces of art (portrayed by other Sesame Street characters) to lead into a song, similar to "Let's Call the Whole Thing Off," about how a lot of different words can mean the same thing.
