As long as you don't take this too seriously, you should be able to get some laughs out of this one.
In terms of game play, its actually extremely shallow. All the game is is side scroller beat-em-up where your goal is to kill 100 enemies. If you put all that aside however, its actually pretty funny to play as your 11 year old brother and shoot tomatoes at your Grandpa on top of a piano. There is a 2 player vs. option, but it is a little awkward. Both players use the same system to fight each other and it usually ends up being the weirdest fight you have ever seen. Overall this game is pretty hilarious and entertaining to play as long as your not expecting the best game you have ever played.
