Absolutely Terrible
Your a smart guy, why come up with your own ideas when you can just steal some audio from a comedian and plaster the Smash Brothers name on it. Ofcourse kids will love it and flood you with 5's.
To the flash itself, it was poorly animated, with terrible lipsync and ugly drawings. The fact Smash Bros had nothing to do with the audio made it even more painful and dissorientating to watch. This was clearly nothing more then a cheap grab for attention.
Enjoy your 5's.
