Voice Activated Christmas Lights [VIDEO]

The other day at my son's birthday party, the place where we had it was just opening up for the day, and the manager was walking around turning on all lights, the machines, and then I saw something weird. The manager started to yell at the Christmas Tree they had set up.

It wasn't an argument. Apparently, he had a voice activated tree that appeared to start up like a charm, as along as you yell at the top of your lungs. "Turn on Christmas lights!" and "Play Jingle Bells!" were just some of the commands that this tree could handle.

As cool as this sounds, is it worth losing your voice over? Man, have we gotten lazy.
