where do ideas come from?

As the end of the year draws near, it's now time to join your co-workers for company parties. Some will risk going to a karaoke (we've all been there, haven't we?).
And it occurred to me that the karaoke is nothing more than a modern version of the old Max Fleischer cartoons with the "famous bouncing ball", which invited us to sing along. I used to watch these cartoons as a kid, and remember sitting in front of the TV absolutely enthralled by that bouncing ball. Here's Popeye singing his theme song (here).
From Popeye and the bouncing ball, we went to this. Enjoy it (and I bet you'll sing along).
