You know when you go to Chuck E. Cheese it's supposed to be fun, right? Lots of games and prizes and good pizza that's what it's about. Unfortunately, at a Chuck E. Cheese in Commack, New Jersey the fun and games turned into an all out brawl.The video footage taken at the popular eatery is pretty nasty but could have been a lot worse because the woman in the video is shown holding a baby when the fight erupts during the singing of Happy Birthday at a children's party. Unbelievable!

The incident is under investigation by authorities. Thinking maybe Chuck E. should have put on a cape and become Mighty Mouse for this one.

Authorities are now investigating the matter.
