I saw this video on Youtube and just couldn't stop watching it. Here is the description on there:
The Scooby Doo Dance Video....A Song We Wrote & Produced By The Harold Jordan Band. With A Little Video We Made to Go Along With It. Music & Lyrics By Harold Jordan & Vic Nielsen. Video By Lee Nielsen. Music & Lyrics Copyrighted 2006.
There is a parade of television characters doing the dance (Scooby is only in it a short time). However, it is down right fun to watch. Warning - the song is catchy and is going to be stuck in your head.
