N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N...BATMAN!!! Need I say more? I could just leave it at that. This theme is one of the most recognizable and simple theme songs there is and will ever be and is certainly one of the funnest themes to sing along to on this list despite the fact that it only really has one word throughout the song (which is even less than The Simpsons). Talking of The Simpsons, one of my favorite moments of all time has to be in the classic episode and one of their very best where The Simpsons join a cult (The Joy of Sect), because of this perfect Batman reference. You know what I am talking about right? N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N... Leader!

Because everyone knows the words to this theme don't they? I bet a lot of you even clap four times at the 10 second mark? This was probably the last great theme tune to an American Sit-com I can think of (I don't watch them all so please in form me if you think I am wrong... maybe "The Big Bang Theory" though I hate the show) and great catchy theme songs used to be a staple of a great American sit-com. This theme is great, but no sit-com theme can beat the show at number one on this list. You know what it is by now don't you?
