Liturgy על פסחים 10:8

What does the wise [son] say? "'What are these testimonies, statutes and judgments that the Lord our God commanded you?' (Deuteronomy 6:20)" And accordingly you will say to him, as per the laws of the Pesach sacrifice, "We may not eat an afikoman [a dessert or other foods eaten after the meal] after [we are finished eating] the Pesach sacrifice (Mishnah Pesachim 10:8)."
