Singing songs that praise G-d (hallel).

This is the time we set aside for singing.  Some of us might sing traditional prayers from the Book of Psalms.  Others take this moment for favorites like Chad Gadya, which you can find at the end of the haggadah.  To celebrate the theme of freedom, we might sing songs from the civil rights movement.  Or perhaps your crazy sibling has some parody lyrics about Passover to the tunes of a musical.  We're at least three glasses of wine into the night, so just roll with it.
