Every Friday, Google holds a company wide meeting named "TGIF." It use to be where the Google co-founders would address the whole company but now I think that the co-founders are not always the ones addressing everyone.
Google's John Mueller was doing a video hangout with a group of webmasters and the clock hit 5pm and music started to play.
John Mueller said that the music plays over the loud speakers through the Google office to remind Googlers to come down to the TGIF meeting. He didn't go, he stayed put, as I suspect many Googlers do. But the music is pretty funny.
It starts at about the 30:54 mark into the video. You can listen to it and then he mutes his microphone and comes back and explains what the music was all about.
Here is a video embed:
Pretty funny!
