I frequently want event tips which are unusual and out of the box. I find that Youtube is without a doubt a wonderful source of such ideas. All you have to do is check out Youtube and do a search for "birthday party ideas" and you will see several hours worth of video clips with countless fabulous points. The problem is, who exactly has enough time to watch them all? Thus I am on a constant quest to gather some details so as to save me and perhaps other people some time.
