Honk! Viv and the kids play a joke on Tony, and down he plops onto a horn. So begins a day of silliness and laughter! Everyone shows off their funny walks, tells jokes, and does things to make each other giggle. They sing about how great it feels to laugh, then meet a court jester who practices being funny for them. They turn Viv into a backwards person, then play out a story about a king who finds out that his daughter is the funniest person in the land.
