I always like to chuckle whenever feminism is brought up, which usually incites said feminist to bring up the seemingly age-old argument, "don't you think women should make the same amount of money as men for equal work?" How does one respond to this in a light-hearted or serious manner?

edit: This got a lot more feedback than I anticipated. From what I've gathered, seems the best course of action is to not even converse with the land whales at all, or for some entertainment value amplify it to an outrageous level.
