This couple has been trying to have a baby but they wont listen to me.?

I told the man 2 things! You see him and his wife have been trying to have a baby for 2 years. I said to him STOP WEARING TIGHTY WHITEYS. his privates needs to breathe and that's why he cant have a a baby because they don't have room down there. And second his wife gained a lot of weight, after she got married, all she has to do is loose 50 pounds and she will look attractive and that will case him to produce more sperm AM I RIGHT??
