3x10 - Rugrats

Angelica asks, ""Where do babies come from?"" Her parents originally planned to give her a well-thought-out answer, but ended up answering ""the stork"". After Angelica tells the Rugrats about this, Tommy finds his new ""brother"", ""Milton"", in the nest, as an unhatched egg. Angelica, however, wants it (""Miltonia"", her new ""sister""), to herself.
