The New Zealand team all do this really funny war-like dance at the start, called the Haka. They pull funny faces, stick their tongues out, slap themselves, and stamp their feet, while making war-like grunting sounds! We all thought it was hilarious!
Billy had his thick winter coat on in the park (we've got no snow yet, unlike some parts of the UK, but it's getting pretty cold now). He then started playing about near the rugby posts in the park, pretending to do his own Haka. I said he was doing the Haka in his parka, and that was it, we both couldn't stop laughing!
(Unfortunately we ended up rolling around on the grass laughing for quite a while, and we got a bit too muddy. Billy's Mum was not very pleased about that, so no hot chocolate to drink when we got home today...)
