In the Sesame version, oviparous animals sing about their reproductive cycle. According to the song, "doves do it, hawks do it, even puffins on the rocks do it." The birds sing together in the chorus: "Let's do it! Let's lay an egg!" In another verse, we learn that snails do it, slugs do it, and even tiny Twiddlebugs do it—a secret of Twiddlebug reproduction that had never been mentioned before.
The song ends with the various animals standing around a nest, cooing as they watch a wide variety of eggs hatching. The animals don't seem concerned that some of the proud parents gathered are predators, some are prey, and one is from a different epoch of Earth's history.
- Performers in the number include Fran Brill, Martin P. Robinson (the snail), Joey Mazzarino (the slug), Jim Martin and Noel McNeal.
- The hawk puppet in this song will later be used as Armstrong the Chicken Hawk in The Animal Show.
