Best episode since the middle of season 1 at least. Aussie vs New Zealander discord may be old material to some viewers but it was hilariously portrayed in this episode. Jemaine deporting Bret because he looked like an Aussie for wearing a vest? I couldn't stop laughing out loud while watching. The two songs are the best I've heard from the duo, with "Too Many Dicks on the Dance Floor" being my personal favorite and almost a guarantee that I buy the season soundtrack.
There are so many memorable lines and scenes, almost the entire thing is quotable, and every recurring character has his scenes. I missed Mel and her take on Jemaine's gf, but I couldn't see room for it.
