Consumer's Make Their Own Ads for Fun

A friend of mine forwarded me this Nintendo related link. Just as a common forwarded email, I watched it, laughed, thought it was cool, forwarded it on to a bunch of people, but it wasn't until a few hours later that I thought... that was pretty much an ad. No logo, no brand name, no annoying announcer, but one hell of a brand recognition.

Here's a Chorus singing for Nintendo. this one's really cool. If anyone has any more, please comment. Looks like Nintendo's agency needs to pay attention.

UPDATE:
Mad kudos to littlejohn for mentioning this killer 11 string bass rendition of some classic Mario
