Did the world really need to see Brett Favre's junk? No. Don't text it to a girl you barely know.
Did I really need to see Anthony Weiner's weiner or chest? Nope and neither did the chick he sent it to.
I'm continually baffled about why people who are famous send illicit pictures of themselves to strangers. It's generally not a good idea for ANYBODY, especially someone who is say, in the political arena or gets media attention. Because for all the good things the media attention can bring to your life (and it does bring good things to most so don't let them fool you with this "I never asked for this" crap), it can also take you down.
Here's a good rule of thumb for all celebrities, politicians and others:
If you get bothered in bathrooms for autographs or can get good tables at nice restaurants just for being you, don't send any photos of any bathing suit parts or otherwise embarrassingly skimpy areas out via twitter, facebook, text or other social media outlet.
