Look Around You is a British TV show, and my favorite kind of comedy -- a parody so subtle that it takes a few minutes and a sharp eye to realize it's not the real thing. It's a series of shorts inspired by the educational films of the late 70s and early 80s -- I certainly had to sit through my share -- which mix complete nonsense with real facts so freely that sometimes it's hard to tell the difference, especially when the subject is something that generally makes no sense to me anyway, like math. The music, old-skool graphics, costumes, and even the muted color of the film all perfectly recall rainy days and substitute teachers, with a delicious edge of madness. For those of you with a pencil and paper handy, this video includes three math problems -- complete them while you're watching, then see if you got the right answers at the end of the video!
