He got what he deserved. Physical violence for a joke is ridiculous. I understand there is slightly more nuance to it as his (cheating) “wife” didn’t entirely chose her hair style and it was due to medical issues but getting up on stage and hitting someone should never be condoned. If a random member of the public did that to someone they would definitely get charged for assault.
She seems like a terrible person in general. Dating her son’s friends etc. So gross.
