Completing an order to hit my balls 150 times with a rubber mallet

Good morning. It's early morning. I just got up and when I checked my messages I saw a message that I have to hit my balls 150 times.

But not only hit, I have to hit it with a rubber wallet.

I've never done so many hits. I'm not sure if I can take it.

But I will do my best. Let me be sure it will not hurt much.

I hope I can count what I hit. I will do perhaps 10 and then make a break.
