Finite Simple Group (of Order Two)

I am a mathematician, I think I already mentioned that. As such, I enjoy the occasional mathematical joke, although I know that's definitely not what you want to use when it comes to boost up your social life. One of my all-time favourites is "What's a polar bear? It's a Cartesian bear after a coordinate change." :)

However, I recently discovered The Klein Four Group, one of the first a cappella groups of the world of higher mathematics. Five graduate students of the Northwestern University in Evanston/Chicago, IL, sing about life with implicit references to mathematical topics. They may be seen as a bunch of nerds who know how to sing, and they probably are, but I think they sing great!

I don't really like embedded YouTube videos in blogs, but I will make an exception for them today. Let me introduce you The Klein Four Group with their hit Finite Simple Group (of Order Two) (here the lyrics)



The name of the group itself is a pun to this. I hope I didn't scare half of my readers away! Please don't panic, I won't be posting mathematical jokes any more... :)
