It is pretty cool. It reminds me of another one I saw that went like this:

You are an archer and you have to pop three columns of balloons. One column contains $$$2$$$ balloons and the other two columns contain $$$3$$$ balloons. You can pop a balloon from any column, but unfortunately, you can only pop the bottommost balloon in some column. In how many different ways can you pop all the balloons?
