Try and fight him off

You decide to hold back on hitting his weak spot just yet, instead opting to overpower him.

This fails, as the zombie manages to give you a hard shove, sending you on the floor.

You scramble to your knees, the zombie boy approaching fast.

Once you are on your knees, he is right in front of you, his big, denim covered balls practically in your face. Now would be a good time to aim for the nuts.
