This is the hilariously cute moment a little boy got his own back on his older sister by whacking her over the head with a plastic bowling pin.<br /><br />In the clip, which was filmed in Houghton-le-Spring on Saturday, the little girl is bossing her baby brother around when he finally cracks, whips out the bowling pin and bobs her on the head.<br /><br />"Sister had been winding her brother up and he finally gets his own back for once," their mother wrote online.<br /><br />"She was absolutely fine the bowling pin isn't hard and I think she was more shocked he got his own back for the first time," their mother added.<br /><br />"They love to wind each other up but also love each other dearly."<br /><br />++CLIENTS PLEASE NOTE: THIS VIDEO HAS BEEN LOOPED++
