Feeding Bertha

I've decided that feeding Jonah is something like a carnival game.  Have you ever played the Big Bertha game at Chuck E Cheese where you throw plastic balls into a giant puppet mouth?  Like that.  Here are the rules:

1. You only have 2 minutes until the game ends.
2. Try to get as much food into the little mouth as you can.
3. The mouth will open and close at random.  The intervals of openness decrease as time is running out.
4. A penalty will be assessed if the mouth was open to babble, fuss or was otherwise not expecting input.
5. For an added challenge, small hands will swipe at the spoon to divert the food away.
6. The game may break down and end at any moment, in which case you lose all the food.
7. When you finish, instead of dispensing prize tickets, the mouth spits some of the food back on you.

In the end, you realize you would have gotten the same result from throwing pies at a clown's face...
