Do you feel that SNL was wrong with their joke towards domestic violence?

On SNL, they made fun of Tiger Woods being beat up by his wife. It is felt that because a woman is beating a man, it is funny. If it was reverse, it wouldn't be funny. It is true that in our society it is felt differently about a woman beating a man than a man beating a woman. This is no different than the way we feel about a female teacher with a male student and a male teacher with a female student. What is your opinion about this?
