So he tells MTV, which keeps the underwear-themed questions alive:

Sway: I know people have piercings, tattoos. Eric, in particular, is talking about a ban on sagging pants. Do feel like people should be penalized?

Obama: "Here is my attitude: I think people passing a law against people wearing sagging pants is a waste of time. We should be focused on creating jobs, improving our schools, health care, dealing with the war in Iraq, and anybody, any public official, that is worrying about sagging pants probably needs to spend some time focusing on real problems out there. Having said that, brothers should pull up their pants. You are walking by your mother, your grandmother, your underwear is showing. What's wrong with that? Come on. There are some issues that we face, that you don't have to pass a law, but that doesn't mean folks can't have some sense and some respect for other people and, you know, some people might not want to see your underwear — I'm one of them."
