The show is so funny, it's definitely one of my favorites. Jemaine looks a lot like my sisters friend too, which is pretty funny. It's sad that they stopped after two seasons but I understand how hard it could be having to write those songs every week.
The first song in the first episode, The Most Beautiful Girl (In The Room), is probably my favorite. I've watched this video of it so many times, and it never stops being funny. Especially when Jemaine does his dance moves.
