When I was in New Zealand, I was introduced to the utterly hilarious group, Flight of the Conchords.
I googled them when I got home, and I found a YouTube video of the group (two Kiwi guys) performing my favorite song, "Business Time." It's a little off color, though not offensive. If you have an uber-prudish boss or co-worker, I wouldn't recommend you listen at work. Otherwise, it's pretty much rated PG.
