So, I stumbled upon a Brady Bunch marathon the other day, and naturally, I sang along to the theme song every time it played. Now, the theme song is stuck in my head. So, I decided to trek through the building to see how many of my coworkers know one of the most popular theme songs of all-time by memory.

Not only did I want to test their knowledge of the theme song itself, I also hope it is now stuck in their heads.

Watch my coworkers respond to my request to sing the Brady Bunch theme song.

Oh, and since we weren't any help, here's the real theme song.

Now, is the song stuck in your head too?

What TV theme song should I challenge my cohorts with next?
