I seriously think you guys come up with cartoons simply by looking at random objects. You could make a funny cartoon about absolutely every thing in the Universe. I'm looking at a wallet, keys, and a glasses case. If you guys ever make songs about those objects, I want credit! Anyway, this was a great cartoon by itself. I suppose it would be gauche for me to suggest you make a sequel called "Beards".
Seeing as how it had a "Start" button, I thought it would not be an infinite loop, but it was. There seem to be several different animation styles in this. The girl looks like she was inspired by Spumco while the singer looks more standardized. The best part was probably when that girl talked about the different kinds of mustaches. The use of colors and shadings is really well done, too.
...You songs make me go boing boing boing.
I've always loved Weeble
