What did the husband do after beating his TV? He watched it. What? You thought this was gonna to be a wife beating joke? Of course not! Why would he beat his dishwasher?
How would you feel about people making jokes about you?
I'd feel like a dishwasher.
Women who are being beaten are going through a hard time and it is not okay to joke about. Making light about them being beaten can be hurtful, just like you would be hurt if people made a joke about something that caused you pain.
