How many babies does it take to paint a wall? Depends on how hard you can throw.
Oh my, I cannot believe you said that. What would make you say such a thing?
It was only a joke, you shouldn't be so offended.
Making violent jokes about innocent babies is usually considered in poor taste. Can you try to imagine how it would feel for a new parent to hear that about a child? Being a parent is stressful and jokes like that can be hurtful, so it is best practice to place yourself in other people's shoes when making dark jokes such as that.
We must be misunderstanding each other. I don't really care if you think it's hurtful.
The majority of people don't think this "joke" is in good taste. Babies are the most innocent and pure and I can't imagine what it would be like for parents to lose their kids.
